Genesis 19:27

27.And Abraham got up early in the morning. Moses now reverts to Abraham, and shows that he, by no means, neglected what he had heard from the mouth of the angel; for he relates that Abraham came to a place where he might see the judgment of God. For we must not suspect that (as we have lately said respecting Lot’s wife) he trusted more to his own eyes than to the word of God; and that he came to explore, because he was in doubt. But we rather infers from the text, that he, being already persuaded that the angel had not spoken in vain, sought confirmation, by the actual beholding of the event; which confirmation would be useful both to himself and to posterity. And it is not to be doubted, that during the whole night, he suffered severe anguish respecting the safety of his nephew Lot. Whether he became satisfied on this point or note we do not know; yet I rather incline to the conjecture, that he remained anxious about him. And it is possible that, hesitating between hope and fear, he went forward to meet him, in order that he might see whether he wag delivered or not. And although he beholds nothing but the smoke, which generally remains after a great fire; yet this sign is given him from the Lord, for a testimony to posterity, of a punishment so memorable. God indeed designs, that, in the very appearance of the place, a monument of his wrath should exist for ever: but because, through the readiness of the world to cast a doubt upon the judgments of God, it might be easily believed, that such had been the nature of the place from the beginning; or that the change had occurred accidentally; the Lord was pleased to exhibit his act of vengeance before the eyes of Abraham, in order that he might discharge the office of a herald to posterity.
