Job 13:23

Here, I. Job enquires after his sins, and begs to have them discovered to him. He looks up to God, and asks him what was the number of them (How many are my iniquities?) and what were the particulars of them: Make me to know my transgressions, Job 13:23. His friends were ready enough to tell him how numerous and how heinous they were, Job 22:5. "But, Lord," says he, "let me know them from thee; for thy judgment is according to truth, theirs is not." This may be taken either, 1. As a passionate complaint of hard usage, that he was punished for his faults and yet was not told what his faults were. Or, 2. As a prudent appeal to God from the censures of his friends. He desired that all his sins might be brought to light, as knowing they would then appear not so many, nor so mighty, as his friends suspected him to be guilty of. Or, 3. As a pious request, to the same purport with that which Elihu directed him to, Job 34:32. That which I see not, teach thou me. Note, A true penitent is willing to know the worst of himself; and we should all desire to know what our transgressions are, that we may be particular in the confession of them and on our guard against them for the future. II.

The catalogue of my sins ought to be great, to judge from the severity with which God ever anew crushes one already bowed down. Would that He would reckon them up! He then would see how much my calamities outnumber them. sin?--singular, "I am unconscious of a single particular sin, much less many" [UMBREIT].
