If I find in Sodom fifty righteous within the city,.... Sodom is particularly mentioned because Lot dwelt there, and being the metropolis, and the city of greatest note, as Jarchi observes, it is put for the rest; and the sense is, if fifty righteous persons could be found in all the five cities, mercy should be shown them:

then will I spare all the place for their sakes; not Sodom only, but the whole country, of which Sodom was the chief; the Lord takes up and agrees to the number Abraham pitched upon, and grants the request he makes.

And the LORD said, If I find in Sodom {m} fifty righteous within the city, then I will spare all the place for their sakes.

(m) God declares that his judgments were done with great mercy, even though all were so corrupt that not only fifty but ten righteous men could not be found there, and also that the wicked are spared for the sake of the righteous.

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.
