Some Pharisees came up to Jesus, testing Him, and began to question Him whether it was lawful for a man to divorce a wife. 3 And He answered and said to them, “What did Moses command you?” 4 They said, “Moses permitted a man to write a certificate of divorce and send her away.” 5 But Jesus said to them, “Because of your hardness of heart he wrote you this commandment. 6 But from the beginning of creation, God made them male and female. 7 For this reason a man shall leave his father and mother, 8 and the two shall become one flesh; so they are no longer two, but one flesh. 9 What therefore God has joined together, let no man separate.”
