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.And they said,.... By way of reply,

Moses suffered to write a bill of divorcement, and to put her away, Moses did not command them to divorce their wives, only suffered them to do so: and gave orders that if they could not bear that they should live with them, but would divorce them, that they should give them a bill, which should certify, they were so divorced, and then send them out of their houses, free to marry other men; this law, or permission, is in Deuteronomy 24:1, of the form of a bill of divorcement, See Gill on Matthew 5:31.
