3 But he answering said to them, What did Moses command you? 4 And they said, Moses allowed to write a bill of divorce, and to put away. 5 And Jesus answering said to them, In view of your hard-heartedness he wrote this commandment for you; 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 be united to his wife, 8 and the two shall be one flesh: so that they are no longer two but one flesh. 9 What therefore God has joined together, let not man separate. 10 And again in the house the disciples asked him concerning this.

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.
