31:33-40 Job clears himself from the charge of hypocrisy. We are loth to confess our faults, willing to excuse them, and to lay the blame upon others. But he that thus covers his sins, shall not prosper, Pr 28:13. He speaks of his courage in what is good, as an evidence of his sincerity in it. When men get estates unjustly, they are justly deprived of comfort from them; it was sown wheat, but shall come up thistles. What men do not come honestly by, will never do them any good.

Thus of the four clauses in Job 31:38, 39, the first refers to the same subject as the fourth, the second is connected with the third by introverted parallelism. Compare Jas 5:4, which plainly alludes to this passage: compare "Lord of Sabaoth" with Job 31:26 here.
