Judges 6:3-11

3And so it was, when Israel had sown, that the Midianites came up, and the Amalekites, and the children of the east; they came up against them; 4and they encamped against them, and destroyed the increase of the earth, till thou come unto Gaza, and left no sustenance in Israel, neither sheep, nor ox, nor ass. 5For they came up with their cattle and their tents; they came in as locusts for multitude; both they and their camels were without number: and they came into the land to destroy it. 6And Israel was brought very low because of Midian; and the children of Israel cried unto Jehovah.

7And it came to pass, when the children of Israel cried unto Jehovah because of Midian, 8that Jehovah sent a prophet unto the children of Israel: and he said unto them, Thus saith Jehovah, the God of Israel, I brought you up from Egypt, and brought you forth out of the house of bondage; 9and I delivered you out of the hand of the Egyptians, and out of the hand of all that oppressed you, and drove them out from before you, and gave you their land; 10and I said unto you, I am Jehovah your God; ye shall not fear the gods of the Amorites, in whose land ye dwell. But ye have not hearkened unto my voice.

11And the angel of Jehovah came, and sat under the oak which was in Ophrah, that pertained unto Joash the Abiezrite: and his son Gideon was beating out wheat in the winepress, to hide it from the Midianites.
