1 Corinthians 6:16-18

Amplified Bible, Classic Edition

¹⁶ Or do you not know and realize that when a man joins himself to a prostitute, he becomes one body with her? The two, it is written, shall become one flesh.^(A)

¹⁷ But the person who is united to the Lord becomes one spirit with Him.

¹⁸ Shun immorality and all sexual looseness [flee from impurity in thought, word, or deed]. Any other sin which a man commits is one outside the body, but he who commits sexual immorality sins against his own body.
