2 Cor 6:15-17
15 What harmony can there be between Christ and Belial [the devil]? Or what has a believer in common with an unbeliever?
16 What agreement [can there be between] a temple of God and idols? For we are the temple of the living God; even as God said, I will dwell in and with and among them and will walk in and with and among them, and I will be their God, and they shall be My people. [Ex 25:8; 29:45; Lev 26:12; Jer 31:1; Ezek 37:27.]
17 So, come out from among [unbelievers], and separate (sever) yourselves from them, says the Lord, and touch not [any] unclean thing; then I will receive you kindly and treat you with favor, [Isa 52:11.]
