Herd
In the Old Testament the term “herd” is applied to the cattle, the word “flocks” embracing the sheep and goats. As these, with camels, constituted the principal property of the patriarchs, the herdmen held an important office. All the sons of Jacob were introduced to Pharaoh as shepherds, and men whose trade had been to feed cattle (Gen. 46:32; Ex. 10:9; 1 Sam. 21:7). Amos had been a herdmen (Amos 1:1; Amos 7:14). In the New Testament the term “herd” is only applied to the swine that, possessed by the demons, perished in the sea (Matt. 8:30, 32).
