1 Thessalonians 4:3-6 - NKJV
For this is the will of God, your sanctification: that you should abstain from sexual immorality;
that each of you should know how to possess his own vessel in sanctification and honor,
not in passion of lust, like the Gentiles who do not know God;
that 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.
