Matthew 19
7 Ref They say to him, Why then did Moses give orders that a husband might give her a statement in writing and be free from her?
8 Ref He says to them, Moses, because of your hard hearts, let you put away your wives: but it has not been so from the first.
9 Ref And I say to you, Whoever puts away his wife for any other cause than the loss of her virtue, and takes another, is a false husband: and he who takes her as his wife when she is put away, is no true husband to her.
