3 And he answered and said unto them, What did Moses command you? 4 And they said, Moses suffered to write a bill of divorcement, and to put her away. 5 But Jesus said unto them, For your hardness of heart he wrote you this commandment. 6 But from the beginning of the creation, Male and female made he them. 7 For this cause shall a man leave his father and mother, and shall cleave to his wife; 8 and the two shall become one flesh: so that they are no more two, but one flesh. 9 What therefore God hath joined together, let not man put asunder. 10 And in the house the disciples asked him again of this matter.

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.
