1 Corinthians 6:16-18

Darby Translation

¹⁶ Do ye not know that he [that is] joined to the harlot is one body? for the two, he says, shall be one flesh.

¹⁷ But he that [is] joined to the Lord is one Spirit.

¹⁸ Flee fornication. Every sin which a man may practise is without the body, but he that commits fornication sins against his own body.
