Adam Clarke on Job 31:33

If I covered my transgressions as Adam - Here is a most evident allusion to the fall. Adam transgressed the commandment of his Maker, and he endeavored to conceal it; first, by hiding himself among the trees of the garden: "I heard thy voice, and went and Hid myself;" secondly, by laying the blame on his wife: "The woman gave me, and I did eat;" and thirdly, by charging the whole directly on God himself: "The woman which Thou Gavest Me to be with me, She gave me of the tree, and I did eat." And it is very likely that Job refers immediately to the Mosaic account in the Book of Genesis. The spirit of this saying is this: When I have departed at any time from the path of rectitude, I have been ready to acknowledge my error, and have not sought excuses or palliatives for my sin.
