'Ox' in the Bible

Speak unto the children of Israel, saying, Ye shall eat no manner of fat, of ox, or of sheep, or of goat.

What man soever there be of the house of Israel, that killeth an ox, or lamb, or goat, in the camp, or that killeth it out of the camp,

Only the firstling of the beasts, which should be the LORD'S firstling, no man shall sanctify it; whether it be ox, or sheep: it is the LORD'S.
