Gen 3:22 KJV And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
Gill: behold, the man is become as one of us, to know good and evil; which is generally understood as an irony or sarcasm at man's deception by Satan, who promised man, and he expected to be as gods, knowing good and evil; behold the man, see how much like a god he looks, with his coat of skin upon his back, filled with shame and confusion for his folly, and dejected under a sense of what he had lost, and in a view of what he was sentenced to; yet must be understood not as rejoicing in man's misery, and insulting over him in it, but in order the more to convince him of his folly, and the more to humble him, and bring him to a more open repentance for affecting what he did, and giving credit to the devil in it:
Others claim the translation should be better as the Hebrew indicates this:
JFB: And God said, Behold, the man is become as one of us — not spoken in irony as is generally supposed, but in deep compassion. The words should be rendered, “Behold, what has become [by sin] of the man who was as one of us”! Formed, at first, in our image to know good and evil - how sad his condition now.
