2 Corinthians 6:14-18
New King James Version
14 Do not be unequally yoked together with unbelievers. For what [a]fellowship has righteousness with lawlessness? And what [b]communion has light with darkness? 15 And what accord has Christ with Belial? Or what part has a believer with an unbeliever? 16 And what agreement has the temple of God with idols? For you[c] are the temple of the living God. As God has said:

“I will dwell in them
And walk among them.
I will be their God,
And they shall be My people.”

17 Therefore

“Come out from among them
And be separate, says the Lord.
Do not touch what is unclean,
And I will receive you.”
18 “I will be a Father to you,
And you shall be My sons and daughters,
Says the Lord Almighty.”
