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.

Now the day after, when they were on their journey and were near the town, Peter went up to the top of the house for prayer, about the sixth hour: And he was in need of food: but while they were getting it ready, a deep sleep came on him; read more. And he saw the heavens opening, and a vessel coming down, like a great cloth let down on the earth, In which were all sorts of beasts and birds. And a voice came to him, saying, Come, Peter; take them for food. But Peter said, No, Lord; for I have never taken food which is common or unclean. And the voice came to him a second time, What God has made clean, do not you make common. And this was done three times: and then the vessel was taken back into heaven.

And a voice came to my ears saying, Come, Peter; take them for food. But I said, No, Lord; for nothing common or unclean has ever come into my mouth.

But now Christ has come as the high priest of the good things of the future, through this greater and better Tent, not made with hands, that is to say, not of this world, And has gone once and for ever into the holy place, having got eternal salvation, not through the blood of goats and young oxen, but through his blood. For if the blood of goats and oxen, and the dust from the burning of a young cow, being put on the unclean, make the flesh clean: How much more will the blood of Christ, who, being without sin, made an offering of himself to God through the Holy Spirit, make your hearts clean from dead works to be servants of the living God?
