Leviticus 11:27

The same rule was applicable to all these animals: "whoever toucheth the carcase of them shall be unclean until the even," i.e., for the rest of the day; he was then of course to wash himself. Whoever carried their carrion, viz., to take it away, was also unclean till the evening, and being still more deeply affected by the defilement, he was to wash his clothes as well.

The ceremonial law is described by the apostle (Heb 9:9, Heb 9:10) to consist, not only "in gifts and sacrifices," which hitherto have been treated of in this book, but "in meats, and drinks, and divers washings" from ceremonial uncleanness, the laws concerning which begin with this chapter, which puts a difference between some sorts of flesh-meat and others, allowing some to be eaten as clean and forbidding others as unclean. "There is one kind of flesh of men." Nature startles at the thought of eating this, and none do it but such as have arrived at the highest degree of barbarity, and become but one remove from brutes; therefore there needed no law against it. But there is "another kind of flesh of beasts," concerning which the law directs here (Lev 11:1-8), "another of fishes" (Lev 11:9-12), "another of birds" (Lev 11:13-19), and "another of creeping things," which are distinguished into two sorts, flying creeping things (Lev 11:20-28) and creeping things upon the earth (Lev 11:29-43). And the law concludes with the general rule of holiness, and reasons for it (Lev 11:44, etc.).
