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. The words of Job are ended. They end with a bold assertion, that, with respect to accusation against his moral and religious character as the cause for his sufferings, he could appeal to God. But, however confident Job was, we shall see he was mistaken, chap. 40:4,5; 1Jo 1:8. Let us all judge ourselves; wherein we are guilty, let us seek forgiveness in that blood which cleanseth from all sin; and may the Lord have mercy upon us, and write his laws in our hearts!

The words … ended—that is, in the controversy with the friends. He spoke in the book afterwards, but not to them. At Job 31:37 would be the regular conclusion in strict art. But Job 31:38-40 are naturally added by one whose mind in agitation recurs to its sense of innocence, even after it has come to the usual stopping point; this takes away the appearance of rhetorical artifice. Hence the transposition by Eichorn of Job 31:38-40 to follow Job 31:25 is quite unwarranted.
