Judges 6:3, 5, 33

Whenever the Israelites planted their crops, the Midianites, Amalekites and other eastern peoples invaded the country.

They came up with their livestock and their tents like swarms of locusts. It was impossible to count them or their camels; they invaded the land to ravage it.

Now all the Midianites, Amalekites and other eastern peoples joined forces and crossed over the Jordan and camped in the Valley of Jezreel.
