3 And Pharisees came up to him and tested him by asking, “Is it lawful to divorce one’s wife for any cause?” 4 He answered, “Have you not read that he who made them from the beginning made them male and female, 5 and 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’?i 6 So they are no longer two but one flesh.i What therefore God has joined together, let not man put asunder.” 7 They said to him, “Why then did Moses command one to give a certificate of divorce, and to put her away?” 8 He said to them, “For your hardness of heart Moses allowed you to divorce your wives, but from the beginning it was not so. 9 And I say to you: whoever divorces his wife, except for unchastity,j and marries another, commits adultery; and he who marries a divorced woman, commits adultery.”k

10 The disciples said to him, “If such is the case of a man with his wife, it is not expedient to marry.”
