Judges 8:24-27

24And Gideon said to them, “I would make a request of you, that each one of you give me an earring from his spoil.” For the Midianites had gold earrings, because they were Ishmaelites [who customarily wore them].

25They answered, “We will certainly give them to you.” And they spread out a garment, and every one of them threw an earring there from his spoil.

26And the weight of the golden earrings that he requested was seventeen hundred shekels of gold, apart from the crescent amulets and pendants and the purple garments which were worn by the kings of Midian, and apart from the chains that were on their camels’ necks.

27Gideon made [all the golden earrings into] an ephod [a sacred, high priest’s garment], and put it in his city of Ophrah, and all Israel worshiped it as an idol there, and it became a trap for Gideon and his household.
