1 Thessalonians 4:3-7

3For this is the will of God, your sanctification: that you should abstain from sexual immorality;

4that each of you should know how to possess his own vessel in sanctification and honor,

5not in passion of lust, like the Gentiles who do not know God;

6that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified.

7For God did not call us to uncleanness, but in holiness.
