That the law of Moses should not be broken - In order that the law requiring it to be done at a specified time, though that might occur on the Sabbath, should be kept.
Are ye angry ... - The argument of Jesus is this: “You yourselves, in interpreting the law about the Sabbath, allow a work of necessity to be done. You do that which is necessary as an ordinance of religion denoting separation from other nations, or external purity. As you allow this, you ought also, for the same reason, to allow that a man should be completely restored to health - that a work of much more importance should be done.” We may learn here that it would be happy for all if they would not condemn others in that thing which they allow. People often accuse others of doing things which they themselves do in other ways.
Every whit whole - Literally, “I have restored the whole man to health,” implying that the man’s whole body was diseased, and that he had been entirely restored to health.
