'Locusts' in the Bible

For they came up with their livestock and their tents; they came in as locusts for multitude; both they and their camels were without number: and they came into the land to destroy it.

The Midianites and the Amalekites and all the children of the east lay along in the valley like locusts for multitude; and their camels were without number, as the sand which is on the seashore for multitude.
