101 And he got up, and went into the country of Judaea on the other side of Jordan: and great numbers of people came together to him again; and, as was his way, he gave them teaching. 2 And Pharisees came to him, testing him with the question, Is it right for a man to put away his wife? 3 And he said to them in answer, What did Moses say you were to do? 4 And they said to him, Moses let us give her a statement in writing, and be free from her. 5 But Jesus said to them, Because of your hard hearts he gave you this law. 6 But from the first, male and female made he them. 7 For this cause will a man go away from his father and mother, and be joined to his wife; 8 And the two will become one flesh; so that they are no longer two, but one flesh. 9 Let not that which has been joined together by God be parted by man. 10 And in the house the disciples put questions to him again about this thing. 11 And he said to them, Whoever puts away his wife and takes another, is false to his wife; 12 And if she herself puts away her husband and takes another, she is false to her husband.

Commentary on Mark 10:1-12
(Read Mark 10:1-12)
Wherever Jesus was, the people flocked after him in crowds, and he taught them. Preaching was Christ's constant practice. He here shows that the reason why Moses' law allowed divorce, was such that they ought not to use the permission; it was only for the hardness of their hearts. God himself joined man and wife together; he has fitted them to be comforts and helps for each other. The bond which God has tied, is not to be lightly untied. Let those who are for putting away their wives consider what would become of themselves, if God should deal with them in like manner.
