Laws about Animals for Food
11 The Lord spoke again to Moses and to Aaron, saying to them, 2 “Speak to the sons of Israel, saying, ‘These are the creatures which you may eat from all the animals that are on the earth. 3 Whatever divides a hoof, thus making split hoofs, and chews the cud, among the animals, that you may eat. 4 Nevertheless, you are not to eat of these, among those which chew the cud, or among those which divide the hoof: the camel, for though it chews cud, it does not divide the hoof, it is unclean to you. 5 Likewise, the [a]shaphan, for though it chews cud, it does not divide the hoof, it is unclean to you; 6 the [b]rabbit also, for though it chews cud, it does not divide the hoof, it is unclean to you; 7 and the pig, for though it divides the hoof, thus making a split hoof, it does not chew cud, it is unclean to you. 8 You shall not eat of their flesh nor touch their carcasses; they are unclean to you.
9 ‘These you may eat, whatever is in the water: all that have fins and scales, those in the water, in the seas or in the rivers, you may eat. 10 But whatever is in the seas and in the rivers that does not have fins and scales among all the teeming life of the water, and among all the living creatures that are in the water, they are detestable things to you, 11 and they shall be [c]abhorrent to you; you may not eat of their flesh, and their carcasses you shall detest. 12 Whatever in the water does not have fins and scales is [d]abhorrent to you.
Avoid the Unclean
13 ‘These, moreover, you shall detest among the birds; they are [e]abhorrent, not to be eaten: the [f]eagle and the vulture and the [g]buzzard, 14 and the kite and the falcon in its kind, 15 every raven in its kind, 16 and the ostrich and the owl and the sea gull and the hawk in its kind, 17 and the little owl and the cormorant and the [h]great owl, 18 and the white owl and the [i]pelican and the carrion vulture, 19 and the stork, the heron in its kinds, and the hoopoe, and the bat.
20 ‘All the [j]winged insects that walk on all fours are detestable to you. 21 Yet these you may eat among all the [k]winged insects which walk on all fours: those which have above their feet jointed legs with which to jump on the earth. 22 These of them you may eat: the locust in its kinds, and the devastating locust in its kinds, and the cricket in its kinds, and the grasshopper in its kinds. 23 But all other [l]winged insects which are four-footed are detestable to you.
24 ‘By these, moreover, you will be made unclean: whoever touches their carcasses becomes unclean until evening, 25 and whoever picks up any of their carcasses shall wash his clothes and be unclean until evening. 26 Concerning all the animals which divide the hoof but do not make a split hoof, or which do not chew cud, they are unclean to you: whoever touches them becomes unclean. 27 Also whatever walks on its paws, among all the creatures that walk on all fours, are unclean to you; whoever touches their carcasses becomes unclean until evening, 28 and the one who picks up their carcasses shall wash his clothes and be unclean until evening; they are unclean to you.
29 ‘Now these are to you the unclean among the swarming things which swarm on the earth: the mole, and the mouse, and the [m]great lizard in its kinds, 30 and the gecko, and the [n]crocodile, and the lizard, and the [o]sand reptile, and the chameleon. 31 These are to you the unclean among all the swarming things; whoever touches them when they are dead becomes unclean until evening. 32 Also anything on which one of them may fall when they are dead becomes unclean, including any wooden article, or clothing, or a skin, or a sack—any article [p]of which use is made—it shall be put in the water and be unclean until evening, then it becomes clean. 33 As for any earthenware vessel into which one of them may fall, whatever is in it becomes unclean and you shall break [q]the vessel. 34 Any of the [r]food which may be eaten, on which water comes, shall become unclean, and any [s]liquid which may be drunk in every vessel shall become unclean. 35 Everything, moreover, on which part of their carcass may fall becomes unclean; an oven or a [t]stove shall be smashed; they are unclean and shall continue as unclean to you.36 Nevertheless a spring or a cistern [u]collecting water shall be clean, though the one who touches their carcass shall be unclean. 37 If a part of their carcass falls on any seed for sowing which is to be sown, it is clean. 38 Though if water is put on the seed and a part of their carcass falls on it, it is unclean to you.
39 ‘Also if one of the animals dies which you have for food, the one who touches its carcass becomes unclean until evening. 40 He too, who eats some of its carcass shall wash his clothes and be unclean until evening, and the one who picks up its carcass shall wash his clothes and be unclean until evening.
41 ‘Now every swarming thing that swarms on the earth is detestable, not to be eaten. 42 Whatever crawls on its belly, and whatever walks on all fours, whatever has many feet, in respect to every swarming thing that swarms on the earth, you shall not eat them, for they are detestable. 43 Do not render [v]yourselves detestable through any of the swarming things that swarm; and you shall not make yourselves unclean with them so that you become unclean. 44 For I am the Lord your God. Consecrate yourselves therefore, and be holy, for I am holy. And you shall not make yourselves unclean with any of the swarming things that swarm on the earth.45 For I am the Lord who brought you up from the land of Egypt to be your God; thus you shall be holy, for I am holy.’”
46 This is the law regarding the animal and the bird, and every living thing that moves in the waters and everything that swarms on the earth, 47 to make a distinction between the unclean and the clean, and between the edible creature and the creature which is not to be eaten.
A bit of a long read, but not terribly difficult. As I think I’ve said before, God’s laws weren’t meant to be burdensome, they are for our safety (whether spiritual, or otherwise). Very many of the rules, especially the ones about food, were meant for protection. Here we see a basic lesson on food safety that God gives the Israelites. While there are foods that we eat today on this list, it is not difficult to realize that in the time when God made these provisions, it would have been difficult to cook such things for safe human consumption. For example, most would know that pork (pig meat) must be cooked at a certain temperature, since pigs are very often carriers of harmful bacteria and parasites. They didn’t know about such things, not having the modern equipment, so without such restrictions, it’s very likely folks could have gotten very sick and even died from violating these guidelines.
So, all that to say again, God gives us boundaries for our protection. As CS Lewis might say, they are rules to tell us how the human “machine” was built to work best. Deviation from them may not cause imminent death, but it is risky, and we should think twice (and check our motives) when we are contemplating going against them.
