Genesis 3:1

Why hath God? Hebrew, "Indeed hath God, &c." as if the serpent had overheard Eve arguing with herself, about God's prohibition, with a sort of displeasure and presumption. St. Augustine thinks, she had given some entrance to these passions, and the love of her own power, and hence gave credit to the words of the serpent, de Gen. ad lit. xi. 30. She might not know or reflect that the serpent could not reason thus, naturally; and she had as yet, no idea or dread of the devil. (Lombard, 2 Dist. 21.) This old serpent entered into the most subtle of creatures, and either by very expressive signs, or by the motion of the serpent's tongue, held this delusive dialogue with Eve. Moses relates what happened exteriorily; but from many expressions, and the curse, ver. 15, he sufficiently indicates, that an evil spirit was the latent actor. (Haydock) --- Of every tree. Satan perverts the word of God, giving it an ambiguous turn: in doing which, he has set heretics a pattern, which they follow. (Menochius)
