Bereshis 18:26 Meaning and Commentary

Genesis 18:26

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.

Bereshis 18:26 In-Context

24 Suppose there be fifty tzaddikim within the city; wilt Thou also destroy and not nasa (spare [take away and bear the guilt of, Yeshayah 53:12]) the place lema’an (for the sake of) the fifty tzaddikim that are therein? [IK 3:18]

25 That be far from Thee to do after this manner, to slay the tzaddik with the rasha; and that the tzaddik should be as the rasha, that be far from Thee: Shall not HaShofet Kol Ha’Aretz (the Judge of All the Earth) do mishpat (right)?

26 And Hashem said, If I find in S’dom fifty tzaddikim within the city, then I will spare all the place for their sakes.

27 And Avraham answered and said, Hinei now, I, which am but aphar and ashes, have taken upon me to speak unto Hashem;

28 Suppose there shall lack five of the fifty tzaddikim; wilt Thou destroy all the city for lack of five? And He said, If I find there forty and five, I will not destroy it.
