Job 31:33 - Joseph Benson’s Commentary on the Old and New Testaments

If I covered my transgressions as Adam As Adam did in paradise. By hiding mine iniquity in my bosom In my own breast, and from the sight of all men; or, in secret, as R. Levi renders בחבי, bechobbi. Job alludes to Adam's hiding himself among the trees of the garden, and palliating his sin; a circumstance in the history of the fall, recorded by Moses, Genesis 3:7, and doubtless imparted by the godly patriarchs to their children before Moses's time, and therefore well known to Job, who here says he did not act thus, but was ever ready to acknowledge his errors. The allusion is quite proper and apposite: but if we should render the passage, agreeably to the marginal reading, after the manner of men, it becomes an accusation of others; and the vindication of himself has a mixture of pride in it, which does not suit the character of the speaker.
