Job 2:3

Although thou movedst, etc.] or, 'so that it was in vain thou movedst me against him to destroy him.'

4, 5. Skin for skin, etc.] The precise meaning of the proverb is uncertain, but the general meaning seems to be that as long as a man does not suffer in his own person he will gladly bear the sacrifice of everything else ('skin for skin'). But it is a different matter when his life is endangered. Let Job suffer this last and greatest trial, then his integrity will fail him (so the Adversary insinuates) and he will renounce God. His life the Satan is not permitted to touch, short of that he has full liberty, and uses it.
