However, Sheila gives another scripture reference, from a new earth passage in Isaiah 62:8-9, “The LORD has sworn by his right hand and by his mighty arm: ‘Never again will I give your grain as food for your enemies, and never again will foreigners drink the new wine for which you have toiled; but those who harvest it will eat it and praise the LORD, and those who gather the grapes will drink it in the courts of my sanctuary.’”
Either way, we don't usually think of the tree of life as a grape vine, but I think it totally works and it might have also been one of the traditional Jewish depictions, though I could be entirely confused on that one.
