Mark 10:2–12

²Some Pharisees came to test Him. “Is it lawful for a man to divorce his wife?” they inquired.

³“What did Moses command you?” He replied.

⁴They answered, “Moses permitted a man to write his wife a certificate of divorce and send her away.”^a

⁵But Jesus told them, “Moses wrote this commandment for you because of your hardness of heart. ⁶However, from the beginning of creation, ‘God made them male and female.’^{b 7}‘For this reason a man will leave his father and mother and be united to his wife,^{c 8}and the two will become one flesh.’^d So they are no longer two, but one flesh. ⁹Therefore what God has joined together, let man not separate.”

¹⁰When they were back inside the house, the disciples asked Jesus about this matter. ¹¹So He told them, “Whoever divorces his wife and marries another woman commits adultery against her. ¹²And if a woman divorces her husband and marries another man, she commits adultery.”
