1 Thessalonians 4:3-7

ISV(i) 3 For it is God’s will that you be sanctified: You must abstain from sexual immorality. 4 Each of you must know how to control his own body in a holy and honorable manner, 5 not with passion and lust like the gentiles who do not know God. 6 Furthermore, you must never take advantage of or exploit a brother in this regard, because the Lord avenges all these things, just as we already told you and warned you. 7 For God did not call us to be impure, but to be holy.
