Animal: An organized living creature endowed with sensation. The Levitical law
divided animals into clean and unclean, although the distinction
seems to have existed before the Flood
(Genesis 7:2) The clean could be
offered in sacrifice and eaten. All animals that had not cloven hoofs
and did not chew the cud were unclean. The list of clean and unclean
quadrupeds is set forth in the Levitical law
(Deuteronomy 14:3-20; Leviticus 11:1)ff
