Matthew Henry's Concise Commentary

27:11-23 Job's friends, on the same subject, spoke of the misery of wicked men before death as proportioned to their crimes; Job considered that if it were not so, still the consequences of their death would be dreadful. Job undertook to set this matter in a true light. Death to a godly man, is like a fair gale of wind to convey him to the heavenly country; but, to a wicked man, it is like a storm, that hurries him away to destruction. While he lived, he had the benefit of sparing mercy; but now the day of God's patience is over, and he will pour out upon him his wrath. When God casts down a man, there is no flying from, nor bearing up under his anger. Those who will not now flee to the arms of Divine grace, which are stretched out to receive them, will not be able to flee from the arms of Divine wrath, which will shortly be stretched out to destroy them. And what is a man profited if he gain the whole world, and thus lose his own soul?
