1 Thessalonians 4:3-6

For this is God’s will, your sanctification: that you keep away from sexual immorality, that each of you knows how to control his own body in holiness and honor, not with lustful passions, like the Gentiles, who don’t know God. This means one must not transgress against and take advantage of a brother or sister in this manner, because the Lord is an avenger of all these offenses, as we also previously told and warned you.
