2 Corinthians 6:14

“Be ye not unequally yoked together with unbelievers, etc..] This seems to be an allusion to the law in (<052210>Deuteronomy 22:10) and to be a mystical explanation of it; and is to be understood not as forbidding civil society and converse with unbelievers; for this is impracticable, then must believers needs go out of the world; this the many natural and civil relations subsisting among men make absolutely necessary; and in many cases is both lawful and laudable, especially when there is any opportunity or likelihood of doing them any service in a spiritual way: not is it to be understood as dehorting from entering into marriage contracts with such persons; for such marriages the apostle,…”

“Be not--Greek, "Become not." unequally yoked--"yoked with one alien in spirit." The image is from the symbolical precept of the law (Lev 19:19), "Thou shalt not let thy cattle gender with a diverse kind"; or the precept (Deu 22:10), "Thou shalt not plough with an ox and an ass together." Compare Deu 7:3, forbidding marriages with the heathen; also Co1 7:39. The believer and unbeliever are utterly heterogeneous. Too close intercourse with unbelievers in other relations also is included (Co2 6:16; Co1 8:10; Co1 10:14). fellowship--literally, "share," or "participation." righteousness--the state of the believer, justified by faith. unrighteousness--rather, as always translated elsewhere,…”

“Be ye not unequally yoked together with unbelievers - This is closely connected in sense with the previous verse. The apostle is there stating the nature of the remuneration or recompence which he asks for all the love which he had shown to them. He here says, that one mode of remuneration would be to yield obedience to his commands, and to separate themselves from all improper alliance with unbelievers. “Make me this return for my love. Love me as a proof of your affection, be not improperly united with unbelievers. Listen to me as a father addressing his children, and secure your own happiness and piety by not being unequally yoked with those who are not Christians.” The word which is used…”

“Be not unequally yoked with unbelievers - Christians with Jews or heathens. The apostle particularly speaks of marriage. But the reasons he urges equally hold against any needless intimacy with them. Of the five questions that follow, the three former contain the argument; the two latter, the conclusion. 2 Corinthians 6:15”

“6:14–7:1 The connection between 6:13 and 7:2 has led many scholars to conclude that 6:14–7:1 is an inserted fragment from another letter (perhaps the one mentioned in 1 Cor 5:9). However, this section might just as well be a digression in Paul’s writing, a suitable challenge to the Corinthians to forsake their opposition to Paul and his message. Paul was anxious to see relationships restored; here, Paul draws a picture of believers in Christ forming a holy temple. Believers’ identity as the temple of God motivates the need for harmony among them as well as separation from the impurity of unbelieving attitudes and behaviors. Paul therefore draws the contrast between Christian and pagan…”
