Genesis 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.

Genesis 18:26 In-Context

24 Should there be fifty righteous in the city, wilt thou destroy them? wilt thou not spare the whole place for the sake of the fifty righteous, if they be in it?
25 By no means shalt thou do as this thing so as to destroy the righteous with the wicked, so the righteous shall be as the wicked: by no means. Thou that judgest the whole earth, shalt thou not do right?
26 And the Lord said, If there should be in Sodom fifty righteous in the city, I will spare the whole city, and the whole place for their sakes.
27 And Abraam answered and said, Now I have begun to speak to my Lord, and I am earth and ashes.
28 But if the fifty righteous should be diminished to forty-five, wilt thou destroy the whole city because of the five ? And he said, I will not destroy it, if I should find there forty-five.
