The various forms of uncleanness according to the Mosaic law are enumerated in Le 11-15; Nu 19. The division of animals into clean and unclean was probably founded on the practice of sacrifice. It existed before the Flood (Ge 7:2). The regulations regarding such animals are recorded in Le 11 and De 14:1-21.
The Hebrews were prohibited from using as food certain animal substances, such as (1) blood; (2) the fat covering the intestines, termed the caul; (3) the fat on the intestines, called the mesentery; (4) the fat of the kidneys; and (5) the fat tail of certain sheep (Ex 29:13,22; Le 3:4-9; 9:19; 17:10; 19:26).
The chief design of these regulations seems to have been to establish a system of regimen which would distinguish the Jews from all other nations. Regarding the design and the abolition of these regulations the reader will find all the details in Le 20:24-26; Ac 10:9-16; 11:1-10; Heb 9:9-14.
Of all clean beasts take unto thee seven of every kind, the male and his female, and of unclean beasts a pair, the male and his female:
and take all the fat that covereth the inwards, and the caul that is on the liver, and the two kidneys with the fat that is upon them: and burn them upon the altar.
Then take the fat of the ram and his rump and the fat that covereth the inwards and the caul of the liver and, the two kidneys, and the fat that is upon them and the right shoulder - for that ram is a full offering -
and the two kidneys with the fat that lieth upon the loins; and the caul that is on the liver, they shall take away with the kidneys. And Aaron's sons shall burn them upon the altar with the burnt sacrifice which is upon the wood on the fire. That is a sacrifice of a sweet savour unto the LORD. read more. "'If a man bring a peace offering unto the LORD from of the flock: whether it be male, or female, it shall be without blemish. If he offer a lamb, he shall bring it before the LORD, and put his hand upon his offering's head, and kill it in the door of the tabernacle of witness, and Aaron's sons shall sprinkle the blood thereof round about the altar. And of the peace offering they shall bring a sacrifice unto the LORD: the fat thereof, and the rump altogether, which they shall take off hard by the back bone: and the fat that covereth the inwards and all the fat that is upon the inwards,
and took the fat of the ox and of the ram, the rump and the fat that covereth the inwards and the kidneys and the caul of the liver;
And whatsoever man it be of the house of Israel or of the strangers that sojourn among you that eateth any manner of blood, I will set my face against that soul that eateth blood, and will destroy him from among his people,
"'Ye shall eat nothing with the blood, ye shall use no witchcraft, nor observe dismal days.
But I have said unto you that ye shall enjoy their land, and that I will give it unto you to possess it: even a land that floweth with milk and honey. I am the LORD your God, which have separated you from other nations: that ye should put difference between clean beasts and unclean, and between unclean fowls and them that are clean. Make not your souls therefore abominable with beasts and fowls, and with all manner thing that creepeth upon the ground, which I have separated unto you to hold them unclean. read more. Be holy unto me, for I the LORD am holy and have severed you from other nations: that ye should be mine.
Ye are the children of the LORD your God; cut not yourselves nor make you any baldness between the eyes for any man's death. For thou art a holy people unto the LORD thy God, and the LORD hath chosen thee to be a several people unto himself, of all the nations that are upon the earth. read more. Ye shall eat no manner of abomination. These are the beasts which ye shall eat of: oxen, sheep and goats, hart, roe and bugle, hart goat, unicorn, origen and camelion. And all beasts that cleave the hoof, and slit it into two claws and chew the cud, them ye shall eat. Nevertheless, these ye shall not eat of them that chew cud and of them that divide and cleave the hoof: the camel, the hare and the coney. For they chew cud, but divide not the hoof: and therefore are unclean unto you: and also the swine, for though he divide the hoof, yet he cheweth not cud, and therefore is unclean unto you. Ye shall not eat of the flesh of them nor touch the dead carcasses of them. These ye shall eat of all that are in the waters: All that have fins and scales. And whatsoever hath not fins and scales, of that ye may not eat, for that is unclean unto you. Of all clean birds ye shall eat, but these are they of which ye may not eat: the eagle, the goshawk, the cormorant, the ixion, the vulture, the kite and her kind, and all kind of ravens, the ostrich, the nightcrow, the cuckoo, the sparrowhawk and all her kind, the little owl, the great owl, the back, the bittern, the pye, the stork, the heron, the jay in his kind, the lapwing, the swallow. And all creeping fowls are unclean unto you and may not be eaten of; but of all clean fowls ye may well eat. Ye shall eat of nothing that dieth alone: But thou mayest give it unto the stranger that is in thy city that he eat it, or mayest sell it unto an Alien. For thou art a holy people unto the LORD thy God. Thou shalt not seethe a kid in his mother's milk.
On the morrow as they went on their journey and drew nigh unto the city, Peter went upon the top of the house to pray, about the sixth hour. Then waxed he a hungered, and would have eaten. But while they made ready for him, he fell into a trance, read more. and saw heaven opened, and a certain vessel come down unto him, as it had been a great sheet, knit at the four corners, and was let down to the earth, wherein were all manner of four footed beasts of the earth and vermin and worms, and fouls of the air. And there came a voice to him, "Rise, Peter. Kill and eat." But Peter said, "God forbid Lord, for I have never eaten anything that is common or unclean." And the voice spake unto him again the second time, "What God hath cleansed that make thou not common." This was done thrice; And the vessel was received up again into heaven.
And the Apostles and the brethren that were throughout Jewry heard say that the Heathen had also received the word of God. And when Peter was come up to Jerusalem, they of the circumcision reasoned with him, saying, read more. "Thou wentest into men uncircumcised, and atest with them." Then Peter began and expounded the thing in order to them saying, "I was in the city of Joppa praying, and in a trance I saw a vision; A certain vessel descend, as it had been a large linen cloth, let down from heaven by the four corners; And it came to me: into the which when I had fastened mine eyes I considered and saw fourfooted beasts of the earth, and vermin and worms, and fowls of the air. And I heard also a voice saying unto me, 'Arise Peter, slay and eat.' And I said, 'God forbid Lord, for nothing common or unclean hath at any time entered into my mouth.' But the voice answered me again from heaven, 'Count not thou those things common, which God hath cleansed.' And this was done three times. And all were taken up again into heaven.
which was a similitude for the time then present, and in which were offered gifts and sacrifices that could not make them that minister perfect, as pertaining to the conscience; with meats only and drinks, and divers washings, and justifyings of the flesh, which were ordained until the time of reformation. read more. But Christ being a high priest of good things to come, came by a greater, and a more perfect tabernacle, not made with hands: that is to say, not of this manner building, neither by the blood of goats, and calves: but by his own blood, we entered once for all into the holy place, and found eternal redemption. For if the blood of oxen, and of goats, and the ashes of a heifer, when it was sprinkled, purified the unclean, as touching the purifying of the flesh: How much more shall the blood of Christ - which through the eternal spirit, offered himself without spot to God - purge your consciences from dead works, for to serve the living God?
