Rashi on Genesis 18:22/רש"י על בראשית י״ח:כ״ב

1ויפנו משם AND [THE MEN] TURNED FROM THENCE —from the place where Abraham had accompanied them.

2'ואברהם עודנו עומד לפני ה BUT ABRAHAM STOOD YET BEFORE THE LORD — But surely it was not he (Abraham) who had gone to stand before Him, but it was the Holy One, blessed be He, Who had come to him and had said to him, “Because the cry of Sodom and Gomorrah is great” and it should therefore have written here, “And the Lord stood yet before Abraham”? But it is a variation such as writers make to avoid an apparently irreverent expression (Genesis Rabbah 49:7) (which our Rabbis, of blessed memory, altered, writing it thus).
