1 Thessalonians 4:3-7

3For it is God’s will that you should be holy: You must abstain from sexual immorality; 4each of you must know how to control his own body1 in holiness and honor, 5not in lustful passion like the Gentiles who do not know God; 6and no one should ever violate or exploit his brother in this regard,2 because the Lord will avenge all such acts, as we have already told you and solemnly warned you. 7For God has not called us to impurity, but to holiness.
