2 Corinthians 6:14-18 - Do Not Become Unevenly Yoked With Unbelievers
14 Be not unequally yoked with unbelievers; for what fellowship hath righteousness with unrighteousness? or what communion hath light with darkness? 15 And what concord hath Christ with Belial? or what part hath a believer with an infidel? 16 And what agreement hath the temple of God with idols? Now ye are the temple of the living God, as God hath said, I will dwell in them, and walk in them, and I will be to them a God, and they shall be to me a people. 17 Therefore come out from among them, and be ye separate, and touch not the unclean person, saith the Lord, and I will receive you, 18 And will be to you a Father, and ye shall be to me sons and daughters, saith the Lord Almighty.
