Did I fear a great multitude, or did the contempt of families {y} terrify me, that I kept {z} silence, and went not out of the door?

(y) That is, I reverenced the most weak and contemned and was afraid to offend them.

(z) I suffered them to speak evil of me, and went not out of my house to avenge it.

Wesley's Notes

31:34 Did I fear - No: all that knew Job knew him to be a man of resolution, that boldly appeared, spoke and acted, in defence of religion and justice. He durst not keep silence, or stay within, when called to speak or act for God. He was not deterred by the number, or quality, or insults of the injurious, from reproving them, and doing justice to the injured.

Jamieson-Fausset-Brown Bible Commentary

34. Rather, the apodosis to Job 31:33, "Then let me be fear-stricken before a great multitude, let the contempt, &c., let me keep silence (the greatest disgrace to a patriot, heretofore so prominent in assemblies), and not go out," &c. A just retribution that he who hides his sin from God, should have it exposed before man (2Sa 12:12). But Job had not been so exposed, but on the contrary was esteemed in the assemblies of the "tribes"-("families"); a proof, he implies, that God does not hold him guilty of hiding sin (Job 24:16, contrast with Job 29:21-25).

Matthew Henry's Concise Commentary

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!
