Judges 6:3, 5, 33

For it was when Israel had sown, that the Midianites would come up with the Amalekites and the sons of the east and go against them.

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

Then all the Midianites and the Amalekites and the sons of the east assembled themselves; and they crossed over and camped in the valley of Jezreel.
