2 Corinthians 6:14-18 - Do Not Become Unevenly Yoked With Unbelievers
14 Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness? 15 What agreement has Christ with Belial? Or what portion has a believer with an unbeliever? 16 What agreement has a temple of God with idols? For you are a temple of the living God. Even as God said, "I will dwell in them, and walk in them; and I will be their God, and they will be my people." 17 Therefore, "'Come out from among them, and be separate,' says the Lord. 'Touch no unclean thing. I will receive you. 18 I will be to you a Father. You will be to me sons and daughters,' says the Lord Almighty."
