“It is a Tree of Life for those who hold fast to it, and all its supporters are praiseworthy! Its ways are of delight and all of its paths are of peace. Bring us back to You, Lord, and we shall return. Renew our days as of old.” (Traditional Blessing when returning the Sefer Torah to the Ark)
The Tree of Life, as mentioned in the Torah, stood in the paradise of Gan Eden (the Garden of Eden) along side the Tree of Knowledge, and all trees of the earth that bore fruit.
