Why the serpent tells the woman lies, saying, "God has said, Ye shall not eat of every tree in the Paradise," when, on the contrary, what God really had said was, "Ye shall eat of every tree in the Paradise, except one?" (Genesis 3:4).
It is the custom for contending arguers to speak falsely in an artful manner, in order to produce ignorance of the real facts, as was done in this case, since the man and woman had been commanded to eat of all the trees but one. But this insidious prompter of wickedness coming in, says that the order which they had received was that they should not eat of them all. He brought forward an ambiguous statement as a slippery stumbling-block to cause the soul to trip. For this expression, "Ye shall not eat of every tree," means in the first place either, not even of one, which is false; or, secondly, not of every one, as if he intended to say, there are some of which you may not eat, which is true. Therefore he asserts such a falsehood more explicitly.
