'Locust' in the Bible

for they and their cattle come up, with their tents; they come in as the fulness of the locust for multitude, and of them and of their cattle there is no number, and they come into the land to destroy it.

and Midian and Amalek, and all the sons of the east are lying in the valley, as the locust for multitude, and of their camels there is no number, as sand which is on the sea-shore for multitude.
