11:1-47 What animals were clean and unclean. - These laws seem to have been intended, 1. As a test of the people's obedience, as Adam was forbidden to eat of the tree of knowledge; and to teach them self-denial, and the government of their appetites. 2. To keep the Israelites distinct from other nations. Many also of these forbidden animals were objects of superstition and idolatry to the heathen. 3. The people were taught to make distinctions between the holy and unholy in their companions and intimate connexions. 4. The law forbad, not only the eating of the unclean beasts, but the touching of them. Those who would be kept from any sin, must be careful to avoid all temptations to it, or coming near it. The exceptions are very minute, and all were designed to call forth constant care and exactness in their obedience; and to teach us to obey. Whilst we enjoy our Christian liberty, and are free from such burdensome observances, we must be careful not to abuse our liberty. For the Lord hath redeemed and called his people, that they may be holy, even as he is holy. We must come out, and be separate from the world; we must leave the company of the ungodly, and all needless connexions with those who are dead in sin; we must be zealous of good works devoted followers of God, and companions of his people.

13-19. these are they which ye shall have in abomination among the fowls—All birds of prey are particularly ranked in the class unclean; all those which feed on flesh and carrion. No less than twenty species of birds, all probably then known, are mentioned under this category, and the inference follows that all which are not mentioned were allowed; that is, fowls which subsist on vegetable substances. From our imperfect knowledge of the natural history of Palestine, Arabia, and the contiguous countries at that time, it is not easy to determine exactly what some of the prohibited birds were; although they must have been all well known among the people to whom these laws were given.

the ossifrage—Hebrew, "bone-breaker," rendered in the Septuagint "griffon," supposed to be the Gyp�tos barbatus, the Lammer Geyer of the Swiss—a bird of the eagle or vulture species, inhabiting the highest mountain ranges in Western Asia as well as Europe. It pursues as its prey the chamois, ibex, or marmot, among rugged cliffs, till it drives them over a precipice—thus obtaining the name of "bone-breaker."

the ospray—the black eagle, among the smallest, but swiftest and strongest of its kind.
