Judges 6:3-5

3Whenever the Israelites planted their crops, the Midianites, Amalekites and other eastern peoples invaded the country. 4They camped on the land and ruined the crops all the way to Gaza and did not spare a living thing for Israel, neither sheep nor cattle nor donkeys. 5They 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.
