Matthew 19:3-8

3Then some Pharisees came and tested Him by asking, “Is it lawful for a man to divorce his wife for any reason?”

4Jesus answered, “Have you not read that from the beginning the Creator ‘made them male and female,’1 5and said, ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh’2? 6So they are no longer two, but one flesh. Therefore what God has joined together, let man not separate.”

7“Why then,” they asked, “did Moses order a man to give his wife a certificate of divorce and send her away?3”

8Jesus replied, “Moses permitted you to divorce your wives because of your hardness of heart. But it was not this way from the beginning.
