“And lest, when I come again, my God will humble me among you, and that I shall bewail many which have sinned already, and have not repented of the uncleanness and fornication and lasciviousness which they have committed.”
King James Version (KJV)
12:21 Who had sinned before - My last coming to Corinth. Uncleanness - Of married persons. Lasciviousness - Against nature.
2Co 12:21 [And] lest . . . my God will humble me among you. Lest he be humiliated by the prevalence of sensual sins also. The uncleanness and fornication and lasciviousness. The sins here named are the peculiar Gentile sins which he has rebuked so severely in both epistles.
