American Standard Version (ASV):
lest again when I come my God should humble me before you, and I should mourn for many of them that have sinned heretofore, and repented not of the uncleanness and fornication and lasciviousness which they committed.
King James Version (KJV):
[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.
