Matthew 19:2-9

2And great multitudes followed Him, and He healed them there.

3The Pharisees also came to Him, testing Him, and saying to Him, “Is it lawful for a man to divorce his wife for just any reason?”

4And He answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’

5and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’?

6So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.”

7They said to Him, “Why then did Moses command to give a certificate of divorce, and to put her away?”

8He said to them, “Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so.

9And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery.”
