1 Corinthians 6:18 in the World English Bible
Flee sexual immorality! “Every sin that a man does is outside the body,” but he who commits sexual immorality sins against his own body.
Context
17 But he that is joined unto the Lord is one spirit.
18 Flee fornication. Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body.
19 What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own?
