Mark 10:6-9

New Revised Standard Version Catholic Edition

⁶ But from the beginning of creation, ‘God made them male and female.’ ⁷ ‘For this reason a man shall leave his father and mother and be joined to his wife,^{[a] 8} and the two shall become one flesh.’ So they are no longer two, but one flesh. ⁹ Therefore what God has joined together, let no one separate.”
