22:5-12 God's providence extends itself to the smallest affairs, and his precepts do so, that even in them we may be in the fear of the Lord, as we are under his eye and care. Yet the tendency of these laws, which seem little, is such, that being found among the things of God's law, they are to be accounted great things. If we would prove ourselves to be God's people, we must have respect to his will and to his glory, and not to the vain fashions of the world. Even in putting on our garments, as in eating or in drinking, all must be done with a serious regard to preserve our own and others' purity in heart and actions. Our eye should be single, our heart simple, and our behaviour all of a piece.
6, 7. If a bird's nest chance to be before thee—This is a beautiful instance of the humanizing spirit of the Mosaic law, in checking a tendency to wanton destructiveness and encouraging a spirit of kind and compassionate tenderness to the tiniest creatures. But there was wisdom as well as humanity in the precept; for, as birds are well known to serve important uses in the economy of nature, the extirpation of a species, whether of edible or ravenous birds, must in any country be productive of serious evils. But Palestine, in particular, was situated in a climate which produced poisonous snakes and scorpions; and the deserts and mountains would have been overrun with them as well as immense swarms of flies, locusts, mice, and vermin of various kinds if the birds which fed upon them were extirpated [Michaelis]. Accordingly, the counsel given in this passage was wise as well as humane, to leave the hen undisturbed for the propagation of the species, while the taking of the brood occasionally was permitted as a check to too rapid an increase.
