The first comes from a midrash called B’reishit Rabbah, part of a many-volume compilation of rabbinic comments covering several books of the Bible. In this one, a fifth-century collection of midrash to Genesis, we find a discussion of the various kinds of trees that must have existed in the Garden of Eden. God tells Adam and Eve that they may not eat from a particular tree, “the tree of knowledge of good and evil” (Genesis 2:18), otherwise identified as “the tree in the middle of the garden” (Genesis 3:3). But all the other trees were available for their pleasure, and the Rabbis musingly wonder what they were. This was Eden, after all-pure paradise. Surely Eden had trees that far excelled the ones we now know.
Rabbi Z’ira thinks Eden was so perfect that it contained “bread trees as large as the cedars of Lebanon.” He draws his lesson from the fact that when Adam and Eve are expelled from the garden, God says, “Because you ate of the tree of which I commanded you, saying, ‘You shall not eat of it’…by the sweat of your brow shall you get bread to eat.’ Rabbi Z’ira concludes that before the expulsion they must not have had to bake their own bread.

: "Then Jesus said to them, 'Most assuredly, I say to you, Moses did not give you the bread from heaven, but My Father gives you the true bread from heaven.'"
