'Locusts' in the Bible

For they would come up with their cattle and their tents, coming like locusts for number; both they and their camels could not be counted; so that they wasted the land as they came in.

And the Mid'ianites and the Amal'ekites and all the people of the East lay along the valley like locusts for multitude; and their camels were without number, as the sand which is upon the seashore for multitude.
