1 Corinthians 6:16 in the World English Bible
Or don’t you know that he who is joined to a prostitute is one body? For, “The two”, he says, “will become one flesh.”
Context
15 Know ye not that your bodies are the members of Christ? shall I then take the members of Christ, and make them the members of an harlot? God forbid.
16 What? know ye not that he which is joined to an harlot is one body? for two, saith he, shall be one flesh.
17 But he that is joined unto the Lord is one spirit.
