6 That no man go beyond and defraud
6 that no one transgress and wrong his brother in this matter, because the Lord is an avenger in all these things, as we told you beforehand and solemnly warned you.
6 Don't run roughshod over the concerns of your brothers and sisters. Their concerns are God's concerns, and he will take care of them. We've warned you about this before.
6 that no one should take advantage of and defraud his brother in this matter, because the Lord is the avenger of all such, as we also forewarned you and testified.
6 Never harm or cheat a fellow believer in this matter by violating his wife, for the Lord avenges all such sins, as we have solemnly warned you before.
Matthew Henry's Commentary on 1 Thessalonians 4:6
Commentary on 1 Thessalonians 4:1-8
(Read 1 Thessalonians 4:1-8)
To abide in the faith of the gospel is not enough, we must abound in the work of faith. The rule according to which all ought to walk and act, is the commandments given by the Lord Jesus Christ. Sanctification, in the renewal of their souls under the influences of the Holy Spirit, and attention to appointed duties, constituted the will of God respecting them. In aspiring after this renewal of the soul unto holiness, strict restraint must be put upon the appetites and senses of the body, and on the thoughts and inclinations of the will, which lead to wrong uses of them. The Lord calls none into his family to live unholy lives, but that they may be taught and enabled to walk before him in holiness. Some make light of the precepts of holiness, because they hear them from men; but they are God's commands, and to break them is to despise God.
