Do not be unequally yoked with unbelievers. For what partnership can righteousness have with wickedness? Or what fellowship does light have with darkness?
KJV
Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
ASV
Be not unequally yoked with unbelievers: for what fellowship have righteousness and iniquity? or what communion hath light with darkness?
