Judges 6:3, 5, 33

For it was whenever Israel had sown [their seed] that the Midianites would come up with the Amalekites and the people of the east and go up against them.

For they would come up with their livestock and their tents, and they would come in as numerous as locusts; both they and their camels were innumerable. So they came into the land to devastate it.

Then all the Midianites and the Amalekites and the people of the east assembled together; and they crossed over [the Jordan] and camped in the Valley of Jezreel.
