1 Corinthians 6:16

16Or do you not know that he who is joined
Or  who holds fast (compare Genesis 2:24 and Deuteronomy 10:20); also verse 17
to a prostitute becomes one body with her? For, as it is written, b“The two will become one flesh.”

Ephesians 5:28

28In the same way chusbands should love their wives as their own bodies. He who loves his wife loves himself.
