Mark 10:8

New Revised Standard Version Updated Edition 2021

and the two shall become one flesh.’ So they are no longer two but one flesh.

See the chapter Copy

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

Therefore a man leaves his father and his mother and clings to his wife, and they become one flesh.

Do you not know that whoever is united to a prostitute becomes one body with her? For it is said, “The two shall be one flesh.”

Therefore what God has joined together, let no one separate.”
