That no man overreach, nor deceive his brother in business. The Protestant and Mr. N. even in their translations, add, in any matter, because some expound it of frauds and circumventions in any kind of business. But this addition of any, should be left out, seeing the best interpreters expound it of a prohibition of adultery, and the injury thereby done to another, and of sins of that kind only, which is confirmed by what follows and what goes before. See St. Jerome in chap. iv. ad Ephes. tom. 4. p. 369.; St. Chrysostom serm. 3 on this place. Here, says he, he speaks of adultery, as before of fornication See Theodoret, Theophylactus, Estius, Menochius, Cornelius a Lap ide (Witham)

Do you call him brother, and wrongest him, and that in things which are unlawful? Here he speaks concerning adultery, but above also concerning all fornication. For since he was about to say, That no man transgress and wrong his brother, Do not think, he says, that I say this only in the case of brethren; you must not have the wives of others at all, nor even women that have no husbands, and that are common. You must abstain from all fornication; Because, he says, the Lord is an avenger in all these things. He exhorted them first, he shamed them, saying, even as the Gentiles. Then from reasonings he showed th...
