Matthew 19:5-8

Murdock(i) 5 And he said: For this reason, a man shall leave his father and his mother, and adhere to his wife; and they two shall be one flesh. 6 Wherefore they were not two, but one flesh. What therefore God hath united, let not man sunder. 7 They say to him: Why then did Moses command to give a bill of divorce, and to put her away? 8 He said to them: Moses, on account of the hardness of your heart, permitted you to divorce your wives: but from the beginning it was not so.
