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.

For if the blood of goats and bulls, and the sprinkling of defiled persons with the ashes of a heifer, sanctify for the purification of the flesh, how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.
