1 Thessalonians 4:3-6

For the purpose of God for you is this: that you may be holy, and may keep yourselves from the desires of the flesh; So that every one of you may keep his body holy and in honour; Not in the passion of evil desires, like the Gentiles, who have no knowledge of God; And that no man may make attempts to get the better of his brother in business: for the Lord is the judge in all these things, as we said to you before and gave witness.
