On leaving those parts he came into the regions of Judea and Transjordan; and when a crowd gathered round him once again, he followed his usual practice and taught them.
The question was put to him: “Is it lawful for a man to divorce his wife?” This was to test him.
He asked in return, “What did Moses command you?”
They answered, “Moses permitted a man to divorce his wife by note of dismissal.”
Jesus said to them, “It was because you were so unteachable that he made this rule for you; but in the beginning, at the creation, God made them male and female. For this reason a man shall leave his father and mother, and be made one with his wife; and the two shall become one flesh. It follows that they are no longer two individuals; they are one flesh. What God has joined together, man must not separate.”
When they were indoors again the disciples questioned him about this matter; he said to them, “Whoever divorces his wife and marries another commits adultery against her; so too, if she divorces her husband and marries another, she commits adultery.”
