Thou shalt not sacrifice ... any bullock, or sheep, wherein is blemish - Under the name of bullock were comprehended bulls, cows, and calves; under that of sheep, rams, lambs, kids, he- and she-goats. An ox, from mutilation, was inadmissible. The qualifications required in animals destined for sacrifice are described (Exo 12:5; Lev 1:3).
