Skin for skin. — This is a more extreme form of the insinuation of Job 1:9. He means Job takes care to have his quid pro quo; and if the worst come to the worst, a man will give up everything to save his life. If, therefore, Job can save his life at the price of subservience to God, he will willingly pay that price rather than die; but his service is worth no more than that selfish object implies.
