Who’s Bible are your reading, Luther’s?
From Mark; Chapter 10:
[2] And the Pharisees coming to him asked him: Is it lawful for a man to put away his wife? tempting him. [3] But he answering, saith to them: What did Moses command you? [4] Who said: Moses permitted to write a bill of divorce, and to put her away. [5] To whom Jesus answering, said: Because of the hardness of your heart he wrote you that precept.
[6] But from the beginning of the creation, God made them male and female. [7] For this cause a man shall leave his father and mother; and shall cleave to his wife. [8] And they two shall be in one flesh. Therefore now they are not two, but one flesh. [9] What therefore God hath joined together, let not man put asunder. [10] And in the house again his disciples asked him concerning the same thing.
[11] And he saith to them: Whosoever shall put away his wife and marry another, committeth adultery against her. [12] And if the wife shall put away her husband, and be married to another, she committeth adultery.
