1 Thessalonians 4:3-8

Goodspeed(i) 3 It is God's will that you should be consecrated, that you abstain from immorality, 4 that each of you learn to take a wife for himself from pure and honorable motives, 5 not to gratify his passion, like the heathen who know nothing of God. 6 No one is to wrong or defraud his brother in this matter, for the Lord avenges all such things, as we told you before, in the most solemn terms. 7 God has not called us to an unclean life, but to a pure one. 8 So whoever disregards this is not disregarding man, but God, who gives you his holy Spirit.
