2 Corinthians 6:14-18 - Do Not Become Unevenly Yoked With Unbelievers
14 Be not strangely yoked with unbelievers; for what fellowship hath righteousness with unrighteousness? Or what communion hath light with darkness? 15 And what concord hath Christ with Beliar? Or what part hath a believer with an unbeliever? 16 And what agreement hath the temple of God with idols? For ye are the temple of the living God; as God said: "I will dwell among them, and walk among them; and I will be their God, and they shall be my people." 17 "Wherefore come out from the midst of them, and be separated, saith the Lord, and touch not anything unclean;" "and I will receive you, 18 and will be to you a father, and ye shall be my sons and daughters, saith the Lord Almighty."
