2 Corinthians 6:14-18 - Do Not Become Unevenly Yoked With Unbelievers
14 Be not unequally yoked with infidels; for what participation hath righteousness with unrighteousness? and what fellowship [is there] between light and darkness? 15 and what concord of Christ with Belial? or what share hath he that believeth with an infidel? 16 or what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, "I will inhabit in them, and walk about in them; and I will be their God, and they shall be for me a people." 17 "Wherefore go forth from the midst of them, and be ye separated, saith the Lord, and touch not the unclean; and I will receive you, 18 and I will be as a father unto you, and ye shall be to me for sons and daughters, saith the Lord Almighty."
