'Herd' in the Bible

Now there was, a great way off from them, a herd of many swine feeding;

and the demons besought him, saying, If thou cast us out, send us away into the herd of swine.

And he said to them, Go. And they, going out, departed into the herd of swine; and lo, the whole herd of swine rushed down the steep slope into the sea, and died in the waters.
