Bullock

(1.) The translation of a word which is a generic name for
horned cattle (Isa. 65:25). It is also rendered "cow" (Ezek.
4:15), "ox" (Gen. 12:16).

(2.) The translation of a word always meaning an animal of the
ox kind, without distinction of age or sex (Hos. 12:11). It is
rendered "cow" (Num. 18:17) and "ox" (Lev. 17:3).

(3.) Another word is rendered in the same way (Jer. 31:18). It
is also translated "calf" (Lev. 9:3; Micah 6:6). It is the same
word used of the "molten calf" (Ex. 32:4, 8) and "the golden
calf" (1 Kings 12:28).

(4.) In Judg. 6:25; Isa. 34:7, the Hebrew word is different.
It is the customary word for bulls offered in sacrifice. In Hos.
14:2, the Authorized Version has "calves," the Revised Version
"bullocks."
