Job 42:8 - Joseph Benson’s Commentary on the Old and New Testaments

Therefore take now seven bullocks, &c. To make an atonement for what you have said amiss. It seems they were each of them to bring seven bullocks and seven rams, which were to be wholly offered up to God as a burnt-offering; for before, the law of Moses, all sacrifices, even those of atonement, appear to have been wholly burned, and therefore were called burnt-offerings. They thought, doubtless, that they had spoken wonderfully well, and had done a righteous act in pleading God's cause; but they are told quite the contrary, that God was displeased with them, required a sacrifice from them, and threatened, if they did not bring it, he would deal with them according to their folly. Many times is God angry at that in us which we ourselves are ready to be proud of; and sees much amiss in that which we think was well done. And go to my servant Job Whom, though you condemned him as a hypocrite, I own for my faithful servant. And offer up a burnt-offering By the hand of Job, whom I hereby constitute your priest, to pray and sacrifice for you. Lest I deal with you after your folly Lest my just judgment take hold of you for your false and foolish speeches.
