1 Thessalonians 4:3-7

3 For this is the will of God: your sanctification, that you abstain from sexual immorality,  4 that each one of you know how to possess himself of his own vessel in sanctification and honor,  5 not in the passion of lust, even as the Gentiles who don't know God;  6 that no one should take advantage of and wrong a brother or sister in this matter; because the Lord is an avenger in all these things, as also we forewarned you and testified.  7 For God called us not for uncleanness, but in sanctification.
