1 Corinthians 6:16-18

Young's Literal Translation

¹⁶ have ye not known that he who is joined to the harlot is one body? `for they shall be -- saith He -- the two for one flesh.'

¹⁷ And he who is joined to the Lord is one spirit;

¹⁸ flee the whoredom; every sin -- whatever a man may commit -- is without the body, and he who is committing whoredom, against his own body doth sin.
