CHAPTER 42
Job Repents
Then Job answered Yahweh, 2I know that You can do all things, and that no purpose of Yours can be restrained. 3You asked, ‘Who is this who hides counsel without knowledge?’ Therefore I have uttered that which I did not understand, things too wonderful for me, which I didn’t know. 4You said, ‘Listen, now, and I will speak; I will question you, and you will answer Me’. 5I had heard of You by the hearing of the ear, but now my eye sees You. 6Therefore I abhor myself, and repent in dust and ashes.
Job Is Restored
7It was so, that after Yahweh had spoken these words to Job, Yahweh said to Eliphaz the Temanite, My wrath is kindled against you, and against your two friends; for you have not spoken of Me the thing that is right, as My servant Job has. 8Now therefore, take to yourselves seven bulls and seven rams, and go to My servant Job, and offer up for yourselves a burnt offering; and My servant Job shall pray for you, for I will accept him, that I not deal with you according to your folly. For you have not spoken of me the thing that is right, as My servant Job has. 9So Eliphaz the Temanite, Bildad the Shuhite and Zophar the Naamathite went, and did what Yahweh commanded them, and Yahweh accepted Job. 10Yahweh turned the captivity of Job, when he prayed for his friends. Yahweh gave Job twice as much as he had before. 11Then came there to him all his brothers, and all his sisters, and all those who had been of his acquaintance before, and ate bread with him in his house. They comforted him, and consoled him concerning all the evil that Yahweh had brought on him. Each one also gave him a piece of money, and each one a ring of gold. 12So Yahweh blessed the latter end of Job more than his beginning. He had fourteen thousand sheep, six thousand camels, one thousand yoke of oxen and a thousand female donkeys. 13He had also seven sons and three daughters. 14He called the name of the first, Jemimah; and the name of the second, Keziah; and the name of the third, Keren Happuch. 15In all the land were no women found so beautiful as the daughters of Job. Their father gave them an inheritance among their brothers. 16After this Job lived one hundred and forty years, and saw his sons, and his sons’ sons, to four generations. 17So Job died, being old and full of days.

Commentary

42:2 Job came to realize the massive practical extent of what he had previously known in theory, what he had "by the hearing of the ear". Now his eye saw / perceived that truly no plan of God can be thwarted, by any of the various 'Satan' monsters imagined by men. We too may say that we believe in the omnipotence of God; but such a belief requires us to throw out all beliefs in supernatural satan figures. And that's not a merely intellectual exercise; to see the tragedies and cruelties of our lives as being ultimately from God and under His control is something which shakes us to the core.
42:5 My eye sees You- All the theory we may know about God must be transformed into personal relationship with God- and that is the purpose of the sufferings of our lives. 
42:7 Although Job did not speak wrongly about God (see too 2:10) and kept patiently speaking the word of God despite the mockery it brought from the friends (James 5:10,11), this does not mean that Job or all that he said was blameless. The friends are not reprimanded for speaking wrongly about Job, but about God. Thus there was probably a fair degree of truth in their accusations concerning Job’s self righteousness. Elihu also severely rebukes him for this, and unlike the three friends he is not rebuked for anything in the final analysis by God in Job 42; not to mention the accusation of 'darkening counsel without knowledge' (38:2) by God Himself, backed up by four chapters of heavy reprimand of Job's reliance on human strength and wisdom. This led to Job retracting much of what he had said (40:4,5; 42:3-6). This clearly establishes that much of Job's reasoning was faulty, although what he spoke before God was correct. Therefore the final comment that God had spoken of God “the thing that is right” could refer to his final repentance. To repent is to admit that God is right; to refuse to repent is to effectively declare Him wrong. And all his wrong understanding and hard words about God were overlooked because of that.
42:15 Gave them an inheritance among their brothers- Job’s understanding of the value and meaning of the human person meant that he valued his daughters as much as his sons, and gave them equal inheritances- unusual, surely, for those days.
