Mark 10

4 They said, "Moses permitted a man to write a certificate of divorce, and to put her away."

5 And Jesus answered and said to them, "In view of your hardheartedness he wrote this commandment for you. 6 But from the beginning of the 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,’ 8 ‘and the two shall become one flesh’; so then they are no longer two, but one flesh. 9 Therefore what God has united together, let not man separate."
