'Locusts' in the Bible

They would invade with their livestock and tents, swooping in as numerous as locusts. It was impossible to count them or their camels and they came into the land to destroy it.

The Midianites, the Amalekites, and certain groups from the east lay encamped in the valley, as thick as locusts. The number of their camels couldn't be calculated they seemed as numerous as the sand on the seashore.
