Judges 6:3, 5, 33

So it was, whenever Israel had sown, Midianites would come up; also Amalekites and the people of the East would come up against them.

For they would come up with their livestock and their tents, coming in as numerous as locusts; both they and their camels were without number; and they would enter the land to destroy it.

Then all the Midianites and Amalekites, the people of the East, gathered together; and they crossed over and encamped in the Valley of Jezreel.
