Judges 6:3, 5, 33

And so it was, when Israel had sown, that the Midianites came up, and the Amalekites, and the children of the east; they came up against them

For they came up with their cattle 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.

Then all the Midianites and the Amalekites and the children of the east assembled themselves together; and they passed over, and encamped in the valley of Jezreel.
