Mark 10:8

Holman Christian Standard Bible

and the two will become one flesh. So they are no longer two, but one flesh.

See the chapter Copy

This is why a man leaves his father and mother and bonds with his wife, and they become one flesh.

Therefore what God has joined together, man must not separate.”

Don’t you know that anyone joined to a prostitute is one body with her? For Scripture says, The two will become one flesh.

In the same way, husbands are to love their wives as their own bodies. He who loves his wife loves himself.
