'Locusts' in the Bible

When they invaded with their cattle and tents, they were as thick as locusts. Neither they nor their camels could be counted. They came to devour the land.

Now the Midianites, Amalekites, and the people from the east covered the valley like a swarm of locusts. Their camels could not be counted; they were as innumerable as the sand on the seashore.
