2 Corinthians 6:14; Be Ye Not Unequally Yoked
2 Corinthians 6:14 Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
Calling to mind the injunction in Deuteronomy 22:10 “Thou shalt not plow with an ox and an ass together”, the Apostle Paul The ox was a clean animal and the donkey unclean, and their step and pull are unequal. [MacDonald]
Oxen and donkeys pulled differently, so plowing a straight line would have been nearly impossible. Drawing a spiritual principle from the literal command, Paul argues that it is a mistake to hitch together a believer and an unbeliever in a close relationship that requires pulling together in a unified direction—whether marriage, business, or any other formal, longer-term contractual or covenant relationship. Why? Because believers and unbelievers have different goals, different worldviews, different methods, and different rules.¹ [Swindoll]
