Matthew 19:4-6

New Revised Standard Version Catholic Edition

⁴ He answered, “Have you not read that the one who made them at the beginning ‘made them male and female,’ ⁵ and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’? ⁶ So they are no longer two, but one flesh. Therefore what God has joined together, let no one separate.”
