Mark 10:5-12

5But Jesus said to them, “12Because of your hardness of heart he wrote you this commandment. 6But 3from the beginning of creation, God 4created them male and female. 75For this reason a man shall leave his father and mother6, 87and the two shall become one flesh; so they are no longer two, but one flesh. 9Therefore, what God has joined together, no person is to separate.”

10And in the house the disciples again began questioning Him about this. 11And He said to them, “8Whoever 9divorces his wife and marries another woman commits adultery against her; 12and 10if she herself 11divorces her husband and marries another man, she is committing adultery.”
