Yahweh said, “Even thus will the children of Israel eat their bread unclean, among the nations where I will drive them.” Ezekiel 4:13

Yahweh spoke to Moses and to Aaron, saying to them,   “Speak to the children of Israel, saying, ‘These are the living things which you may eat among all the animals that are on the earth.   Whatever parts the hoof, and is cloven-footed, and chews the cud among the animals, that you may eat.   “‘Nevertheless these you shall not eat of those that chew the cud, or of those who part the hoof: the camel, because he chews the cud but doesn’t have a parted hoof, he is unclean to you.   The cony, because he chews the cud but doesn’t have a parted hoof, he is unclean to you.  The hare, because she chews the cud but doesn’t part the hoof, she is unclean to you.  The pig, because he has a split hoof, and is cloven-footed, but doesn’t chew the cud, he is unclean to you.   Of their meat you shall not eat, and their carcasses you shall not touch; they are unclean to you.   “‘These you may eat of all that are in the waters: whatever has fins and scales in the waters, in the seas, and in the rivers, that you may eat.   All that don’t have fins and scales in the seas, and in the rivers, of all that move in the waters, and of all the living creatures that are in the waters, they are an abomination to you,   and you shall detest them. You shall not eat of their meat, and you shall detest their carcasses.  Whatever has no fins nor scales in the waters, that is an abomination to you.  “‘These you shall detest among the birds; they shall not be eaten, they are an abomination: the eagle, and the vulture, and the black vulture, 
 and the red kite, any kind of black kite, 
 any kind of raven, 
 the horned owl, the screech owl, and the gull, any kind of hawk, 
 the little owl, the cormorant, the great owl, 
 the white owl, the desert owl, the osprey, 
 the stork, any kind of heron, the hoopoe, and the bat. 
 “‘All flying insects that walk on all fours are an abomination to you.   Yet you may eat these: of all winged creeping things that go on all fours, which have legs above their feet, with which to hop on the earth.  Even of these you may eat: any kind of locust, any kind of katydid, any kind of cricket, and any kind of grasshopper.   But all winged creeping things which have four feet, are an abomination to you.  “‘By these you will become unclean: whoever touches their carcass shall be unclean until the evening.  Whoever carries any part of their carcass shall wash his clothes, and be unclean until the evening.  “‘Every animal which parts the hoof, and is not cloven-footed, nor chews the cud, is unclean to you. Everyone who touches them shall be unclean.  Whatever goes on its paws, among all animals that go on all fours, they are unclean to you. Whoever touches their carcass shall be unclean until the evening.   He who carries their carcass shall wash his clothes, and be unclean until the evening. They are unclean to you.  “‘These are they which are unclean to you among the creeping things that creep on the earth: the weasel, the rat, any kind of great lizard,  the gecko, and the monitor lizard, the wall lizard, the skink, and the chameleon.   These are they which are unclean to you among all that creep. Whoever touches them when they are dead, shall be unclean until the evening.  On whatever any of them falls when they are dead, it shall be unclean; whether it is any vessel of wood, or clothing, or skin, or sack, whatever vessel it is, with which any work is done, it must be put into water, and it shall be unclean until the evening; then it will be clean.   Every earthen vessel, into which any of them falls, all that is in it shall be unclean, and you shall break it.  All food which may be eaten, that on which water comes, shall be unclean; and all drink that may be drunk in every such vessel shall be unclean.  Everything whereupon part of their carcass falls shall be unclean; whether oven, or range for pots, it shall be broken in pieces: they are unclean, and shall be unclean to you.  Nevertheless a spring or a cistern in which water is gathered shall be clean: but that which touches their carcass shall be unclean.   If part of their carcass falls on any sowing seed which is to be sown, it is clean.   But if water is put on the seed, and part of their carcass falls on it, it is unclean to you.  “‘If any animal, of which you may eat, dies; he who touches its carcass shall be unclean until the evening.  He who eats of its carcass shall wash his clothes, and be unclean until the evening. He also who carries its carcass shall wash his clothes, and be unclean until the evening.  “‘Every creeping thing that creeps on the earth is an abomination. It shall not be eaten.  Whatever goes on its belly, and whatever goes on all fours, or whatever has many feet, even all creeping things that creep on the earth, them you shall not eat; for they are an abomination.  You shall not make yourselves abominable with any creeping thing that creeps. You shall not make yourselves unclean with them, that you should be defiled thereby.  For I am Yahweh your God. Sanctify yourselves therefore, and be holy; for I am holy. You shall not defile yourselves with any kind of creeping thing that moves on the earth.  For I am Yahweh who brought you up out of the land of Egypt, to be your God. You shall therefore be holy, for I am holy.  “‘This is the law of the animal, and of the bird, and of every living creature that moves in the waters, and of every creature that creeps on the earth,  to make a distinction between the unclean and the clean, and between the living thing that may be eaten and the living thing that may not be eaten.’” Leviticus 11

You shall not eat any abominable thing. 
These are the animals which you may eat: the ox, the sheep, the goat, 
the deer, the gazelle, the roebuck, the wild goat, the ibex, the antelope, and the chamois. 
Every animal that parts the hoof, and has the hoof cloven in two and chews the cud, among the animals, that may you eat. 
Nevertheless these you shall not eat of them that chew the cud, or of those who have the hoof cloven: the camel, the hare, and the rabbit. Because they chew the cud but don’t part the hoof, they are unclean to you. 
The pig, because it has a split hoof but doesn’t chew the cud, is unclean to you. You shall not eat their meat, and you shall not touch their carcasses. These you may eat of all that are in the waters: whatever has fins and scales may you eat. 
You shall not eat whatever doesn’t have fins and scales. It is unclean to you. 
Of all clean birds you may eat. But these are they of which you shall not eat: the eagle, the vulture, the osprey, 
the red kite, the falcon, the kite after its kind, 
every raven after its kind, 
the ostrich, the owl, the seagull, the hawk after its kind, 
the little owl, the great owl, the horned owl, 
the pelican, the vulture, the cormorant, 
the stork, the heron after its kind, the hoopoe, and the bat. 
All winged creeping things are unclean to you. They shall not be eaten. 
Of all clean birds you may eat. 
You shall not eat of anything that dies of itself. You may give it to the foreigner living among you who is within your gates, that he may eat it; or you may sell it to a foreigner; for you are a holy people to Yahweh your God. You shall not boil a young goat in its mother’s milk.  Deuteronomy 14:3-21

“I am inquired of by those who didn’t ask. I am found by those who didn’t seek me. I said, ‘See me, see me,’ to a nation that was not called by my name.  I have spread out my hands all day to a rebellious people, who walk in a way that is not good, after their own thoughts;  a people who provoke me to my face continually, sacrificing in gardens, and burning incense on bricks;  who sit among the graves, and spend nights in secret places; who eat pig’s meat, and broth of abominable things is in their vessels; who say, ‘Stay by yourself, don’t come near to me, for I am holier than you.’ These are smoke in my nose, a fire that burns all day.  Isaiah 65:1-5

“Those who sanctify themselves and purify themselves to go to the gardens, behind one in the middle, eating pig’s meat, abominable things, and the mouse, they shall come to an end together,” says Yahweh.  Isaiah 66:17
