1 Samuel 20:24-27

So David hid in the field; and when the new moon came, the king sat down to eat food. 25The king sat on his seat as usual, the seat by the wall; then Jonathan rose up and Abner sat down by Saul’s side, but David’s place was empty. 26Nevertheless Saul did not speak anything that day, for he thought, “It is an accident, he is not clean, surely he is not clean.” 27It came about the next day, the second day of the new moon, that David’s place was empty; so Saul said to Jonathan his son, “Why has the son of Jesse not come to the meal, either yesterday or today?” (NASB)

It seems that in Ancient Israel they celebrated the New Moon festival for two days: the day of the New Moon and the following day. But why did they celebrate the second day of the month? The text in Numbers 28:11 doesn't at all indicate that the New moon is to be celebrated for two days, and there is no reason to suspect that the new moon is different than all the other biblical festivals which don't last for two days either (with the exception of Passover and Succoth).

Was the occurrence in Samuel an out of the ordinary thing (if so I would like to know what the reason was), or perhaps an indication that the New Moon festival was celebrated differently in Ancient Israel?

The text in Samuel itself suggests that the New Moon festival was not yet over by the second day. This can be gleaned from the awkward phrase ממחרת החדש השני which very much sounds like, "the second day of the New Moon festival", or as the NASB renders it "the next day, the second day of the new moon". However most translations have them as two separate clauses, that is, "the day after the new moon" (ממחרת החדש), and "the second day of the month" (השני), an interpretation which doesn't sit so well with me. This perhaps should be asked as a wholly separate question; namely, how ought we interpret these words?

I would appreciate any insight on the hermeneutical and exegetical implications of this verse as well.

  • Supposing the new moon occurred a day prior to the Sabbath could they not have been celebrating two different events. (Not sure why having meals together is directly connected to the new moon. They had meals separately on non new moon days?) Feb 16, 2019 at 12:46

    The month was a malai. They celebrated two days just like Jews do today. Oct 31, 2022 at 21:02

The Hebrew New Moon
חֹ֙דֶשׁ֙ means month, monthly, moon, or new moon. Biblically, there are two types of New Moon observations, one in the seventh month and all others:

Unlike the new moon of the seventh month, which was...celebrated with a great festival, the regular monthly new moons were subordinate feast days celebrated with additional burnt offerings (Num 28:11-15), the blowing of trumpets (Num 10:10; Ps 81:3), family feasts (I Sam 20:5), spiritual edification (II Kgs 4:23), and family Sacrifices (I Sam 20:6).1

The Hebrew New Moon is not the time during which the moon is not visible; it is the day of the first sighting of the waxing crescent which appears shortly after sunset. Its main significance was to set the first day of the month in order to observe the annual festivals on the proscribed day:

The moon occupied an important place in the life of the Hebrews, since it was the guide to their calendar based on the lunar month or period of the moon's circuit. Because of this, and the importance of the uniform celebration of the various periodic religious festivals by Jews everywhere, it was extremely important to determine the exact time of the appearance of the new moon. Thus the appearance of the smallest crescent signified the beginning of the new month and was announced with the blowing of the shofar or ram's horn.2

Identifying the time (the Hebrew day begins at sunset) by observation is an inexact process:

Various factors such as atmospheric pressure, temperature, humidity along the light path, altitude, latitude and longitude, fog, cloud/dust cover, glare etc. can all affect a first sighting. No one can infallibly predict the moment when the new moon will become visible to the naked eye.3

In the Second Temple period, the certainty of the correct day was set by the Sanhedrin:

Of the greatest significance, however, was the proclamation of New Moon ("Ḳiddush ha-Ḥodesh") by the president of the Sanhedrin (R. H. ii. 7) —originally, of course, by the high priest—just as in Rome the Pontifex Maximus fixed New Moon by proclamation (whence the name Calendar). The Sanhedrin was assembled in the courtyard ("bet ya'azek") of Jerusalem on the 30th of each month from morning to evening, waiting for the reports of those appointed to observe the new moon; and after the examination of these reports the president of the Sanhedrin, in the presence of at least three members, called out: "The New Moon is consecrated"; whereupon the whole assembly of people twice repeated the words: "It is consecrated" (R. H. ii. 5-7; Sanh. 102).4

Perhaps owing to its secondary nature, there is little written about a "regular" New Moon festival. Outside of the passage in Samuel, there is a reference in Judith of two days of celebration:

And she fasted all the days of her widowhood, save the eves of the sabbaths, and the sabbaths, and the eves of the new moons, and the new moons and the feasts and solemn days of the house of Israel. (Judith 8:6)

Breaking her fast and rejoicing (some translations) for two consecutive days at the time of the New Moon parallels the episode in Samuel, although they are occur on different days. Here the first day is called the eve of the new moon and the second is νεομηνία, specifically the New Moon.

Two Full Days/On the Third Day
In his translation with commentary Robert Alter says David and Jonathan plan (v.5 and 19) to meet again on the third day after 2-days of celebration:

And David said to Jonathan, “Look, it is the new moon tomorrow, and I am supposed to sit with the king to eat. Let me go and I shall hide in the field till the evening of the day after tomorrow.
(1 Samuel 20:5)

the new moon. In early biblical times, this was an important festival. Sacrifices were offered, ceremonial feasts were held, and ordinary business was not transacted.

the day after tomorrow. The Masoretic Text has "the third evening," treating hashelishit as an adjective modifying "evening," though it has the wrong gender suffix. It is more likely a noun meaning the day after tomorrow (the day on which one speaks being day one in the sequence of three). One should then read 'erev hashelishit instead of the Masoretic ha'erev haselishit. In any case, the number three will play an important role as the episode develops.5

The day after tomorrow you will go all the way down and come to the place where you hid on the day of the deed and stay by the Ezel stone. (1 Samuel 20:19)

Verse 19: The day after tomorrow. The Masoretic vocalization weshilashta treats this as a verb (to do something a third time or in a third instance), but it is more plausible to vocalize it as a noun, ushelishit, "and on the third day."6

Samuel offers no details as to how the New Moon was signaled. Presumably this was done by Ahimelech, the High Priest in Nob (not too far from Gibeath where the meals take place). Regardless of how, the passage shows David and Johnathan's plans were made before the New Moon was signaled and with the foreknowledge there would be two consecutive days of celebration.

The first meal takes place after the sighting and so it is at night:

So David hid himself in the field. And when the new moon came, the king sat down to eat food. (20:24) [ESV]

The "new moon came" and the king "sat down to eat." The first meal did not began until after the sighting of the crescent: this meal celebrated the actual sighting. That the first meal took place on the night of the sighting is reinforced by stating the next meal was after the new moon:

But on the second day, the day after the new moon, David's place was empty...(20:27)

The description of the events raise two issues:

  1. How did David and Jonathan know there would be a New Moon before the actual sighting?
  2. Why was there a second meal the day after the sighting?

Lunar Phases
Today a "new" moon means the phase in which there is no visible light. So the Hebrew New Moon comes the night after what is now called a new moon. No one planning to celebrate the sighting had to wait for the shofar: they could use knowledge of the lunar cycle. David and Jonathan knew the first meal was scheduled for that night because there had been no visible light the night before.

The night of first sighting naturally follows a night of darkness. No visible light is the signal to "get ready" for the Hebrew New Moon. However, occasionally there are months where the moon is not visible for two consecutive nights. For example, in 2018, February 15 and 16, September 9 and 10, and November 7 and 8, were days on which the visible illumination from the moon was 0%. In those months the first sighting will occur on the third night. This is a normal yet variable phenomenon since it occurs in different months each year. In 2019 it happens in February, March, July, and November. Therefore, the signal to "get ready" will mistake the night of an actual sighting approximately 30% of the time (7 of 24 calendar months).7

In months of no visible light for two consecutive nights, there will not be a sighting on the first night: what was reasonably anticipated to happen (70%) will not occur. But the sighting would be certain to occur on the second night of the Festival. This means that festivals scheduled in advance in honor of the New Moon celebration (i.e. immediately after the "no light" signal) must always be planned for 2-days, because of the unpredictability of the lunar phase and of constant fear that the crescent may not be seen on the first night: enter image description here The plans David and Jonathan made show the practice in Saul's kingdom was to prepare for the New Moon Festival before the actual sighting. Since the sighting did happen on the first night, there was no need for the second day; yet the meal of the second night went forward as planned.

A New Moon sighting on the first night and immediately celebrated with a meal makes a second meal the following night unnecessary. Yet the meal on the second night went forward as David and Jonathan expected. The expectation of the second meal, despite of the uncertainty that it would be necessary, can only mean a 2-day observance was the practice, at least at that point in time.

In most months the only significance of the Hebrew New Moon is to celebrate the first sighting of the waxing crescent. Other than additional sacrifices (Numbers 28:11-15) there were no proscribed meal(s) or ritual(s) to observe or celebrate the New Moon. Neither a 1-day or a 2-day Festival is mandated. Perhaps the events in Samuel reflect a practice necessary before establishing Jerusalem as the only place from which the sighting could be proclaimed or, more likely, a practical concession to the difficulty in communicating an official sighting throughout the nation. It is important to remember the New Moon is "common knowledge" which is predictable and happens whether it is officially seen and reported or if/when that report is received.

A 2-day Festival which is scheduled because the moon was not visible (an event seen by all), ensures a celebratory meal will take place on the night of the sighting. The passage in Judith not only describes two days of eating, "House of Israel" suggests a Northern Kingdom practice. That is, the primary significance of the Sanhedrin declaration in Jerusalem was ensuring the calendar was correct and making additional sacrifices, where the practice in the Northern Kingdom, or anywhere outside of Jerusalem, was to simply celebrate the event (knowing the "official" first day of the month would be communicated later and in time to observe either the Passover or the fast for the Day of Atonement).

  • Revelation I see you have edited and changed your response. Are you saying that the Israelites celebrated the day before the sighting and the day of the sighting? Why is that?

  • I also think that the two days of 0 percent illumination is distracting and confusing, and you may as well skip that part. All that is necessary to say is that they prepared a meal the night before the actual sighting (though I am still unclear why they did it). How they anticipated it is irrelevant and confusing to the reader. Just a suggestion.

  • @Bach I believe the 2-days of no illumination is the underlying requirement for a 2-day observance and modified my answer to better explain why that is so. Feb 25, 2019 at 17:42
  • Revelation thanks for your edit. It is much clearer now and I love it! Just one more thing: How do you know that the moon was seen on the fist night in Sam. 20? Maybe it was one of those rare months where the moon was hidden on first day and only visible on second, yet they still celebrated first day as they already prepared for it (just like they would celebrate on second day even when it was already seen on first day)!

The annual feast day on the new moon was Yom Teruah, the Day of Trumpets (Lev. 23:24). Since the destruction of the temple in AD 70, the rabbis began calling it Rosh Hashana, the New Year. The new moon had to be witnessed and declared.

But, because the feast day of Yom Teruah had to wait for the confirmation of the two witnesses, and the declaration of the new moon from the high priest, the feast was always held for two days. The preparations were made ahead of time as much as possible, but they could not always have the declaration on the same day as the new moon. Therefore the feast day was carried over to the second day of the new moon.

"Yom Teruah is always celebrated for two days, even in Israel. These two days are celebrated as though it is just one long day of forty-nine hours.[26]

These days of Yom Teruah are called “yoma arichta” (one long day) to indicate that the sanctity of both is not a doubtful sanctity, but a definite one. See also KNOWDAY.

The reason that we celebrate for two days is because if we waited to start our celebration until after the new moon had been sanctified, we would have missed half the celebration because the new moon can only be sanctified during daylight hours. The new moon is also very difficult to see on the first day because it can be seen only about sunset, close to the sun, when the sun is traveling north. So, looking for a very slim faint crescent moon, which is very close to the sun, is a very difficult thing to do." Source: here

  • @Bach, I think I presumed that the proof you were looking for was the evidence of the scripture text you used for the question. That Saul celebrated the feast meal the 2nd day in 1 Sam. 20:26-27 is not proof enough?
    – Gina
    Nov 4, 2018 at 23:46
  • Gina these verses prove that they celebratedthe new moon for 2 days. The question is why? Your answer is that it was Rosh Hashana (and that they celebrated this festival 2 days back than), a claim which is highly speculative and virtually unsupported. The more accepted Jewish traditional explanation is that it was a regular Rosh Chodesh and that the Israelites celebrated them for 2 days just like they did in the times of the second temple when the chodesh was 'malei' or full, see this jewishvirtuallibrary.org/rosh-chodesh...

The second day was not a feast. It was just the second day of the month and David was missed at the table because that was his place of sitting with the king. There is no two day feast for the new moon. The only such occasion would be a double Sabbath. Which is the seven day Sabbath falling after a feast day like the new moon.

1 Samuel 20:27 And it came to pass on the morrow, which was the second day of the month, that David's place was empty: and Saul said unto Jonathan his son, Wherefore cometh not the son of Jesse to meat, neither yesterday, nor to day?

It was just the second day of the month and David was missed because that was his seat at the table with the king where he dined regularly.

  • Yes. Welcome to BHSE! Please make sure you take our tour. Thanks Dec 31, 2020 at 18:08
  • David if you look at my question you can see that I mention this interpretation and also that I'm not happy with this translation, since the text clearly indicates that the morrow after New moon was part of the celebration. That's what השני clearly implies, i.e., the second celebration or the second day of the festival. IMO the KJV in this case is not very loyal to the text. If you speak Hebrew you will understand that this is the case. In any case, you're welcome to post your own answer as long as you provide good compelling evidence. As of now your post can still be improved a lot.

  • Also look at the title of the question: "Why did they celebrate again the day after the New Moon in 1 Samuel 20:27?" If you believe there was only one day of New moon of festival you will have to explain why they celebrated the day after. If it was just a regular supper the king ate every day, Saul wouldn't be wondering why David didn't show up once again.

  • @Bach The Hebrew says השני this is referring to the day of the month. See how prophets such as Ezekiel use ordinal numbers to refer to the day of a month. חדש, the word for "new moon" also means "month." The hebrew reads as ממחרת החדש השני. The first two words mean "from the coming of the new moon." The third means "the second" which is just missing the word for day because that word isn't necessary. Many other translations also translate it as the second day of the month. If you want to read it as one phrase you would have to read it as "from the coming of the second month."

The point there is this, Saul wouldn't have expected David the second day if celebration was not to take place because David was not living with Saul .

Therefore , it appears that in Israel at he time wee observing two days new moon even either for purpose of not missing out in exact time of moon appearance because God had commanded it to be celebrated at the very beginning .so in-between those two days appearance of Moon must have meet them to avoid missing out on the command of Beginning .

If the sighting of the new moon (NM) comes on 29th then the month ends with 29 days then there is only one new moon day feast - NM Day 1 of the following month. If the new moon did not come on the 29th day - the new moon then comes on the 30th day and the month ends with 30 days.

In 1 Sam 20 there are two new moon day feasts - the 30th of the previous month (the 1st day of the new moon feast waiting for sighting on 29th which did not occur) AND NM Day 1 of the following month (the 2nd day of the new moon feast - the NM having been sighted on 30th).

1 Sam 20:27 is a reference to the second day of the new moon as it was not sighted on the first day of the feast (30th). 1 Sam 20:27 uses Gr. μηνος (which can mean crescent moon) not μήνα (month). MT H2320 chodesh also allows for (new moon, month).

David's 3 days of hiding then are the 29th, 30th, and 1st. David then goes to Ahimelech after a further 3 days (2nd, 3rd, 4th) and eats the old shewbread as given to him by Ahimelech then swapped out on the sabbath (5th) for fresh shewbread.

My understanding is that the months were always 30 days back then (before the Great Earthquake in the 8th Century BCE which changed the lunar cycle), so it was known in advance when the New Moon Day was, and that it was also a custom to continue the feast on the second day of the month because there was food leftover from the previous day, especially since back there was no refrigeration and all leftover food had to get eaten.
