Mark 10:4-12

4They said, “Moses permitted a man to write a certificate of divorce and send her away.” 5“It was because your hearts were hard that Moses wrote you this law,” Jesus replied. 6“But at the beginning of creation God ‘made them male and female.’ 7‘For this reason a man will leave his father and mother and be united to his wife, 8and the two will become one flesh.’ So they are no longer two, but one flesh. 9Therefore what God has joined together, let no one separate.” 10When they were in the house again, the disciples asked Jesus about this. 11He answered, “Anyone who divorces his wife and marries another woman commits adultery against her. 12And if she divorces her husband and marries another man, she commits adultery.”
