The Jews have several names for the Feast of Trumpets, or Yom Teruah which God established in Lev. 23:23-25. It is literally a day of remembrance of blowing, or a day of blowing the trumpet. Today, they call it Rosh HaShana for the beginning of the Jewish civil new year, but that is not according to the scriptures. Ex. 12:2 set the beginning of the year as the month of Nisan.
It is also called Yom Hadin, Day of Judgment; as well as Yom Hazikaron, Day of Remembrance. By Rabbinic tradition, they also call it Yom Harat Olam, for the day the world was conceived. The only scriptural name that God gave it was Yom Teruah. The other names may have originated during the Babylonian captivity from the influence of the pagan belief in one day of judgment when all the “gods” gathered to determine the fates of every individual. (1) It began to be called Rosh Hashana after the temple was destroyed, some time about the second century AD.
As Yom Teruah falls on the first day of the seventh month (Tishrei), the feast or holy day had to wait for the High Court (Sanhedrin) to declare it. The Court waited for the report of at least two witnesses to the crescent light, or new moon / new light (2). As a result, the people could not truly know ahead of time which day would be the first day, so they had to prepare and wait for the official declaration. Sometimes, the Court would declare it a little late in the day, and the feast would be extended an extra day to the 2nd day of Tishrei. (3)
But, a saying for this feast became popular with the Jews as “no man knows the day or the hour.” (4) When the disciples heard Jesus use this Hebraic phrase in His Olivet Discourse for the day the temple would be torn down, they would have recognized it as referring to Yom Teruah, or the Feast of Trumpets.
Jesus certainly knew what He was saying to them, and His disciples certainly knew to watch for the first of Tishrei. Jesus did not tell them which first day of Tishrei, which year, or how many years to His second appearance in that generation. But, the Holy Spirit let them know, as both Peter and Paul repeatedly told them in their letters that the day was near and at hand (Rom. 13:11-12; Phil. 4:5; 2 Thess. 2:2; 1 Pet. 4:7).
There were many blasts of the trump on Yom Teruah, but the “last trump” was know as the Tekiah Gedolah, and was a long sustained blast of the shofar.
”In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.” (1 Cor. 15:52, KJV)
It is not an accident that Paul used the phrase the “last trump.” Jesus’ disciples would have also associated that phrase with the Feast of Trumpets on the 1st of Tishrei.
The parable of the wedding feast in Matt. 22:1-14 ties the destruction of Jerusalem to the wedding feast.
”7 But when the king heard thereof, he was wroth: and he sent forth his armies, and destroyed those murderers, and burned up their city. 8 Then saith he to his servants, The wedding is ready, but they which were bidden were not worthy.” (Matt. 22:7-8, KJV)
Judgment occurred at the wedding feast (Matt. 22:11-13). Jesus told His disciples that when He came in His glory, judgment would occur as He would take out all the souls from Hades, and separate them (Matt. 25:31-46). According to tradition, the bridegroom came for His bride in the night – like a thief – with trumpets blowing through the streets. (5) That is why the bride and her bridesmaids (the ten virgins) waited with lamps lighted. They had to have purchased the fuel for the lamps ahead of time as they did not know which night would be THE night.
This also ties having to be prepared before the 1st of Tishrei since they did not know which day would be declared to be the first day of the month.
The common mis-understanding of the future delayed second appearance of the Lord (Heb. 9:28,that Paul said would be in that same generation in which He was crucified) stems from false teaching that there is a separation of the subject matter in Matt. chap. 24 at verse 34. The institutional churches have taught that Jesus changed the subject from the destruction of the temple to the “end of the world” at verse 35 because they do not recognize that the words “heaven and earth” were also a popular saying of the Jews. They called the temple in Jerusalem “heaven and earth” as that is where God met with man. (6)
God used the phrase “heaven and earth” for the old Mosaic covenant as it was a promise between God and man.
”I call heaven and earth to witness against you this day,…" (Deu. 4:26, KJV) and,
”Take this book of the law, and put it in the side of the ark of the covenant of the LORD your God, that it may be there for a witness against thee.” (Deu. 31:26, KJV)
So, when Jesus said in Matt. 24:35 that, “Heaven and earth shall pass away, but my words shall not pass away” He contrasted His words of the new covenant against Moses words of the old covenant. It was not referring the end of the physical cosmos. The subject matter was still of the prophesy of the destruction of that old temple in Jerusalem which happened in AD 70.
If we are using one scripture in such a way that contradicts another of God’s scriptures, then we are misunderstanding His word.
”And the LORD smelled a sweet savour; and the LORD said in his heart, I will not again curse the ground any more for man's sake; for the imagination of man's heart is evil from his youth; neither will I again smite any more every thing living, as I have done.” (Gen. 8:21, KJV)
When Jesus said that the gospel would be preached through “all the world” (Matt. 24:14) and “then end would come” it was the same “all the world” of Luke 2:1, which was the inhabited earth (oikoumene) of the old Roman empire. (7)
Jesus tied it to the tribulation of Dan. 12:1. The prophesy of the “end of the days” of Dan. 12:13 when Daniel would stand in his lot was the end of the days of Daniel’s prophesy of the 490 years in Dan. 9:24. The “end of days” never was about the end of all time, but only about the end of the Mosaic covenant, and the end of the temple sacrifices in Jerusalem.
Jesus knew when, and He knew what He was saying to His disciples. The Father determined when to send the bridegroom for His bride (Rev. 19:7) as He prepared for the battle to destroy that great whore Jerusalem (Rev. 19:2).
