3. Mose 11:39

Lastly, contact with edible animals, if they had not been slaughtered, but had died a natural death, and had become carrion in consequence, is also said to defile (cf. Lev 11:39, Lev 11:40 with Lev 11:24-28). This was the case, too, with the eating of the swarming land animals, whether they went upon the belly, (Note: The large ו in גּחון (Lev 11:42) shows that this vav is the middle letter of the Pentateuch.) as snakes and worms, or upon four feet, as rats, mice, weasels, etc., or upon many feet, like the insects (Lev 11:41-43). Lastly (Lev 11:44, Lev 11:45), the whole law is enforced by an appeal to the calling of the Israelites, as a holy nation, to be holy as Jehovah their God, who had brought them out of Egypt to be a God to them, was holy (Exo 6:7; Exo 29:45-46).

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.).

11:39-40 Israelites were not to consume blood (7:26). They could eat an animal only after the blood had been drained and properly disposed of (17:13). The undrained blood of an otherwise clean animal that died of natural causes rendered it unclean. An Israelite was permitted to give or sell such an animal to foreigners (Deut 14:21) but not to eat it.
