Matthew 19:7-9

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

8Yeshua said to them, “Because of your hardness of heart Moses permitted you to divorce your wives, but from the beginning it was not so.

9Now I tell you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery.”
