'Herd' in the Bible

And there was a good way off from them an herd of many swine feeding.

So the devils besought him, saying, If thou cast us out, suffer us to go away into the herd of swine.

And he said unto them, Go. And when they were come out, they went into the herd of swine: and, behold, the whole herd of swine ran violently down a steep place into the sea, and perished in the waters.
