John spills a bit of ink describing a seemingly pointless detail about a Jew climbing up a fig tree and Philip calling him from below his fig tree:
[Jhn 1:48-50 KJV] (48) Nathanael saith unto him, Whence knowest thou me? Jesus answered and said unto him, Before that Philip called thee, when thou wast under the fig tree, I saw thee. (49) Nathanael answered and saith unto him, Rabbi, thou art the Son of God; thou art the King of Israel. (50) Jesus answered and said unto him, Because I said unto thee, I saw thee under the fig tree, believest thou? thou shalt see greater things than these.
Might this be related to the messianic prophecy in Zechariah?:
[Zec 3:8-10 CSB] (8) "Listen, High Priest Joshua, you and your colleagues sitting before you; indeed, these men are a sign that I am about to bring my servant, the Branch. (9) "Notice the stone I have set before Joshua; on that one stone are seven eyes. I will engrave an inscription on it" -- this is the declaration of the LORD of Armies -- "and I will take away the iniquity of this land in a single day. (10) "On that day, each of you will invite his neighbor to sit under his vine and fig tree." This is the declaration of the LORD of Armies.
I notice that Luke also has Jesus calling Zacchaeus under a fig tree (sycamores are a kind of fig tree):
[Luk 19:1-10 CSB] (1) He entered Jericho and was passing through. (2) There was a man named Zacchaeus who was a chief tax collector, and he was rich. (3) He was trying to see who Jesus was, but he was not able because of the crowd, since he was a short man. (4) So running ahead, he climbed up a sycamore tree to see Jesus, since he was about to pass that way. (5) When Jesus came to the place, he looked up and said to him, "Zacchaeus, hurry and come down because today it is necessary for me to stay at your house." (6) So he quickly came down and welcomed him joyfully. (7) All who saw it began to complain, "He's gone to stay with a sinful man." (8) But Zacchaeus stood there and said to the Lord, "Look, I'll give half of my possessions to the poor, Lord. And if I have extorted anything from anyone, I'll pay back four times as much." (9) "Today salvation has come to this house," Jesus told him, "because he too is a son of Abraham. (10) "For the Son of Man has come to seek and to save the lost."
Another possibly relevant passage is:
[Rev 3:20 KJV] (20) Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.
which I take to refer back to this:
[Gen 18:1-8 NLT] (1) The LORD appeared again to Abraham near the oak grove belonging to Mamre. One day Abraham was sitting at the entrance to his tent during the hottest part of the day. (2) He looked up and noticed three men standing nearby. When he saw them, he ran to meet them and welcomed them, bowing low to the ground. (3) "My lord," he said, "if it pleases you, stop here for a while. (4) Rest in the shade of this tree while water is brought to wash your feet. (5) And since you've honored your servant with this visit, let me prepare some food to refresh you before you continue on your journey." "All right," they said. "Do as you have said." (6) So Abraham ran back to the tent and said to Sarah, "Hurry! Get three large measures of your best flour, knead it into dough, and bake some bread." (7) Then Abraham ran out to the herd and chose a tender calf and gave it to his servant, who quickly prepared it. (8) When the food was ready, Abraham took some yogurt and milk and the roasted meat, and he served it to the men. As they ate, Abraham waited on them in the shade of the trees.
[1Ki 4:25 KJV] (25) And Judah and Israel dwelt safely, every man under his vine and under his fig tree, from Dan even to Beersheba, all the days of Solomon.
[Mic 4:4 KJV] (4) But they shall sit every man under his vine and under his fig tree; and none shall make them afraid: for the mouth of the LORD of hosts hath spoken it.
