And it shall come to pass in that day, that the mountains shall drop down new wine, and the hills shall flow with milk, and all the rivers of Judah shall flow with waters, and a fountain shall come forth from the house of YHWH, and shall water the Valley of Acacias (Joel 4:18, cf. Ezekiel 47:1–12).
“Jacob our father planted at the time he descended to Egypt. He said, ‘My sons, eventually you will be redeemed from this place, and the blessed Holy One will say to you: ‘You will be redeemed,’ so that you may build a sanctuary for Him. Therefore, go plant acacia trees now so that when He commands you to erect a sanctuary for Him, beams of acacia will be available. Immediately they arose and planted as he had commanded them to do” (Tanḥuma 1:9, cf. Bereshit Rabbah 94:4; Ibn Ezra on Exodus 25:5).
For a tree has hope: though cut down, it can still be removed, and it’s shoots will not cease (Job 14:7).
