1 Thessalonians 4:6

“That no man go beyond, and defraud his brother in any matter, etc.] Or “in this matter”, as the Syriac version. This is commonly understood of transgressing the bounds of justice and equity between men and men; and of cheating and defrauding in trade and business, by increasing or lessening the value and prices of goods by the buyer and seller, by not keeping to the bargain, contract, covenant, or sample, by false weights and measures, and by taking the advantage of the weakness and ignorance of men; all which is aggravated by dealing thus with a brother; (see <460608>1 Corinthians 6:8) and this hint is thought the rather necessary, since Thessalonica was a place of great trade and business.…”

“go beyond--transgress the bounds of rectitude in respect to his "brother." defraud--"overreach" [ALFORD]; "take advantage of" [EDMUNDS]. in any matter--rather as Greek, "in the matter"; a decorous expression for the matter now in question; the conjugal honor of his neighbor as a husband, Th1 4:4; Th1 4:7 also confirms this view; the word "brother" enhances the enormity of the crime. It is your brother whom you wrong (compare Pro 6:27-33). the Lord--the coming Judge (Th2 1:7-8). avenger--the Righter. of all such--Greek, "concerning all these things;" in all such cases of wrongs against a neighbor's conjugal honor. testified--Greek, "constantly testified [ALFORD].”

“That no man go beyond - ὑπερβαίνειν huperbainein. This word means, “to make to go over,” as, e. g., a wall or mountain; then, to overpass, to wit, certain limits, to transgress; and then to go too far, i. e., to go beyond right - hence to cheat or defraud. It is not used elsewhere in the New Testament. The idea of overreaching is that which is implied in its use here. And defraud - πλεονεκτεῖν pleonektein Margin, “oppress,” or “overreach.” This word properly means, to have more than another; then to have an advantage; and then to take advantage of any one, to circumvent, defraud, cheat. It is rendered “got an advantage,” 2 Corinthians 2:11; “defraud,” 2 Corinthians 7:2; 1 Thessalonians…”

“In this matter - By violating his bed. The things forbidden, here are three: fornication, Th1 4:3; the passion of desire, or inordinate affection in the married state, Th1 4:5; and the breach of the marriage contract. 1 Thessalonians 4:8”
