Jesus said to them, “He wrote this command for you because you’re heartless. ⁶ But God made them male and female in the beginning, at creation. ⁷ That’s why a man will leave his father and mother and will remain united with his wife, ⁸ and the two will be one. So they are no longer two but one. ⁹ Therefore, don’t let anyone separate what God has joined together.”
(Mark 10:5-9 -- GW)
