Mark the severity, which is loving severity, of Christ's answer. He speaks to all who shared the ruler's thoughts, of whom there were several present (v. 17, 'adversaries'). Piercing words which disclose hidden and probably unconscious sins, are quite in place on the lips into which grace was poured. Well for those who let Him tell them their faults now, and do not wait for the light of judgment to show themselves to themselves for the first time. Wherein lay these men's hypocrisy? They were pretending zeal for the Sabbath, while they were really moved by anger at the miracle, which would have been equally unwelcome on any day of the week. They were pretending that their zeal for the Sabbath was the result of their zeal for God, while it was only zeal for their Rabbinical niceties, and had no religious element in it at all. They wished to make the Sabbath law tight enough to restrain Jesus from miracles, while they made it loose enough to allow them to look after their own interests. Men may be unconscious hypocrites, and these are the most hopeless. We are all in danger of fancying that we are displaying our zeal for the Lord, when we are only contending for our own additions to, or interpretations of, His will. There is no religion necessarily implied in enforcing forms of belief or conduct. Our Lord's defence is, first of all, a conclusive _argumentum ad hominem_, which shuts the mouths of the objectors; but it is much more. The Talmud has minute rules for leading out animals on the Sabbath: An ass may go out with his pack saddle if it was tied on before the Sabbath, but not with a bell or a yoke; a camel may go out with a halter, but not with a rag tied to his tail; a string of camels may be led if the driver takes all the halters in his hand, and does not twist them, but they must not be tied to one another--and so on for pages. If, then, these sticklers for rigid observance of the Sabbath admitted that a beast's thirst was reason enough for work to relieve it, it did not lie in their mouths to find fault with the relief of a far greater human need. But the words hold a wider truth, applicable to our conduct. The relief of human sorrow is always in season. It is a sacred duty which hallows any hour. 'Is not this the fast [and the feast too] that I have chosen ... to let the oppressed go free, and that ye break every yoke?' The spirit of the words is to put the exercise of beneficence high above the formalities of worship.
