30 He said, "Oh don't let the Lord be angry, and I will speak. What if there are thirty found there?" He said, "I will not do it, if I find thirty there."

And he said unto him, Oh, let not the Lord be angry, and I will speak,.... He feared, through his importunity, he should be wearisome to him and incur his displeasure; this being often the case among men, especially when inferiors are soliciting their superiors, and, not content with one favour, are pressing for more:
Peradventure there shall thirty be found there; the abatement is larger than before; he only made an abatement of five at a time, now ten at once, and so he proceeds:
and he said, I will not do it, if I find thirty there; not destroy the place for their sake.
Oh let not the Lord be angry - The importunity which believers use in their addresses to God is such, that if they were dealing with a man like themselves, they could not but fear that he would be angry with them. But he with whom we have to do is God and not man, and he is pleased when he is wrestled with. But why then did Abraham leave off asking when he had prevailed so far as to get the place spared if there were but ten righteous in it? Either, Because he owned that it deserved to perish if there were not so many: as the dresser of the vineyard, who consented that the barren tree should be cut down if one year's trial more did not make it fruitful, Luke 13:9. Or, Because God restrained his spirit from asking any farther. When God hath determined the ruin of a place, he forbids it to be prayed for, Jeremiah 7:16.
