1 Corinthians 6:16-18

Lexham English Bible

¹⁶ Or do you not know that the one who joins himself to a prostitute is one body with her? For it says, “The two will become one flesh.”^{[a] 17} But the one who joins himself to the Lord is one spirit with him. ¹⁸ Flee sexual immorality. Every sin that a person commits is outside his body, but the one who commits sexual immorality sins against his own body.
