Then Job answered the Lord, and said. For though he had said he would answer no more, Job 40:5; yet he might mean not in the manner he had, complaining of God and justifying himself; besides he might change his mind without any imputation of falsehood or a lie; see Jeremiah 20:9; to which may be added, that he had then said all he had to say, and did not know he should have more: he then confessed as much as he was convinced of, but it was not enough; and now through what the Lord had since said to him he was more convinced of his ignorance, mistakes, and sins, and had such a sight of God and of himself, that he could not forbear speaking; moreover an injunction was laid upon him from the Lord to speak again, and therefore he was obliged to give in his answer; see Job 40:7.

Job was now sensible of his guilt; he would no longer speak in his own excuse; he abhorred himself as a sinner in heart and life, especially for murmuring against God, and took shame to himself. When the understanding is enlightened by the Spirit of grace, our knowledge of Divine things as far exceeds what we had before, as the sight of the eyes excels report and common fame. By the teachings of men, God reveals his Son to us; but by the teachings of his Spirit he reveals his Son in us, Galatians 1:16, and changes us into the same image, 2-Corinthians 3:18. It concerns us to be deeply humbled for the sins of which we are convinced. Self-loathing is ever the companion of true repentance. The Lord will bring those whom he loveth, to adore him in self-abasement; while true grace will always lead them to confess their sins without self-justifying.

1 Then Job answered Jehovah, and said:
2 Now I know that Thou canst do all things,
And no plan is impracticable to Thee.
3 "Who then hideth counsel -
Without knowledge?"
Thus have I judged without understanding,
What was too wonderful for me, without knowing.
He indeed knew previously what he acknowledges in Job 42:2, but now this knowledge has risen upon him in a new divinely-worked clearness, such as he has not hitherto experienced. Those strange but wondrous monsters are a proof to him that God is able to put everything into operation, and that the plans according to which He acts are beyond the reach of human comprehension. If even that which is apparently most contradictory, rightly perceived, is so glorious, his affliction is also no such monstrous injustice as he thinks; on the contrary, it is a profoundly elaborated מזמּה, a well-digested, wise עצה of God. In Job 42:3 he repeats to himself the chastening word of Jehovah, Job 38:2, while he chastens himself with it; for he now perceives that his judgment was wrong, and that he consequently has merited the reproof. With לכן he draws a conclusion from this confession which the chastening word of Jehovah has presented to him: he has rashly pronounced an opinion upon things that lie beyond his power of comprehension, without possessing the necessary capacity of judging and perception. On the mode of writing ידעתּ, Cheth., which recalls the Syriac form med'et (with the pronominal suff. cast off), vid., Ges. 44, rem. 4; on the expression Job 42:2, comp. Genesis 11:6. The repetition of Job 38:2 in Job 42:3 is not without some variations according to the custom of authors noticed in Psalter, i. 330. הגּדתּי, "I have affirmed," i.e., judged, is, Job 42:3, so that the notion of judging goes over into that of pronouncing a judgment. The clauses with ולא are circumstantial clauses, Ew. 341, a.
