And the Lord said, Because the cry of Sodom and Gomorrah is great. Literally, the cry of Sodom and Gomorrah (cf. Genesis 4:10), because it is (not, it is indeed, Baumgarten, Keil) multiplied; the place of emphasis being conceded to the subject of discourse, viz; the cry of Sodom's wickedness.
And because their sin is very great. Literally, and their sin, because it is heavy, i.e. abundant and heinous.
