2 Corinthians 6:14-18 - Do Not Become Unevenly Yoked With Unbelievers
14 Be not unequally yoked with unbelievers; for what fellowship has righteousness with lawlessness? what communion has light with darkness? 15 What concord has Christ with Belial? What portion has a believer with an unbeliever? 16 And what compact has God's temple with idols? For we are a temple of the living God, as he has said: I will dwell among them, and walk about among them; I will be their God, and they will be my people. 17 Therefore, Come out from among them and separate yourselves, saith the Lord, touch not what is unclean; 18 then I will receive you and will be to you a Father, and you shall be to me sons and daughters, saith the Lord Almighty.
