And because of that, there is a tree, the branches of which are sweet, but the wood of its branches are bitter. Likewise, there are sweet waters and bitter waters, since the Holy One, blessed be He, created one corresponding to the other. And there is one that one half of it is sweet and one half of it is bitter, and that is the Tree of Knowledge of Good and Evil, just like silver is mixed with lead.
And there is a tree, the husks of which are evil on the outside but its mind is sweet inside. Like this, you will find a person who is evil in the words of his mouth (different variant: and exudes evil from his mouth outside), but he is good in his heart inside; and one who has good from his mouth but his heart is evil. That one is the Tree of Knowledge of Good and Evil, it is there that the deceptive snake nests.
