lest my God should humble me as to you when I come again, and that I shall grieve over many of those who have sinned before, and have not repented as to the uncleanness and fornication and licentiousness which they have practised.

Now the works of the flesh are manifest, which are fornication, uncleanness, licentiousness,

who having cast off all feeling, have given themselves up to lasciviousness, to work all uncleanness with greedy unsatisfied lust.

But fornication and all uncleanness or unbridled lust, let it not be even named among you, as it becomes saints;

Put to death therefore your members which are upon the earth, fornication, uncleanness, vile passions, evil lust, and unbridled desire, which is idolatry.

For our exhortation was not of deceit, nor of uncleanness, nor in guile;
