Verse 32. - And he said, Oh let not the Lord be angry (vide supra), and I will speak but this once (literally, only this time more, as in Exodus 10:17): Peradventure ten shall be found there. And he said, I will not destroy it for ten's sake.

18:23-33 Here is the first solemn prayer upon record in the Bible; and it is a prayer for the sparing of Sodom. Abraham prayed earnestly that Sodom might be spared, if but a few righteous persons should be found in it. Come and learn from Abraham what compassion we should feel for sinners, and how earnestly we should pray for them. We see here that the effectual, fervent prayer of a righteous man avails much. Abraham, indeed, failed in his request for the whole place, but Lot was miraculously delivered. Be encouraged then to expect, by earnest prayer, the blessing of God upon your families, your friends, your neighbourhood. To this end you must not only pray, but you must live like Abraham. He knew the Judge of all the earth would do right. He does not plead that the wicked may be spared for their own sake, or because it would be severe to destroy them, but for the sake of the righteous who might be found among them. And righteousness only can be made a plea before God. How then did Christ make intercession for transgressors? Not by blaming the Divine law, nor by alleging aught in extenuation or excuse of human guilt; but by pleading HIS OWN obedience unto death.And he said, Oh, let not the Lord be angry, and I will speak yet but this once,.... This should be the last request he should make on this account, and therefore he desired he might be heard without any marks of his displeasure:

Peradventure ten shall be found there: how would the place be dealt with then? would it be consumed or not?

and he said, I will not destroy it for ten's sake; though no more righteous persons were found in it. Some of the Jewish writers say (g), he ended at ten, because he supposed there were ten righteous persons in Lot's family, Lot and his wife, and their four daughters, and their four husbands; but they forgot that two of Lot's daughters were unmarried, and how many he had married is not known; ten they say make a congregation, and wherever there are ten righteous persons, a place is saved for their sakes.
