Judges 8:24-27
8:24 Gideon continued, “I would like to make one request. Each of you give me an earring from the plunder you have taken.” (The Midianites had gold earrings because they were Ishmaelites.)
8:25 They said, “We are happy to give you earrings.” So they spread out a garment, and each one threw an earring from his plunder onto it.
8:26 The total weight of the gold earrings he requested came to seventeen hundred gold shekels. This was in addition to the crescent-shaped ornaments, jewelry, purple clothing worn by the Midianite kings, and the necklaces on the camels.
8:27 Gideon used all this to make an ephod, which he put in his hometown of Ophrah. All the Israelites prostituted themselves to it by worshiping it there. It became a snare to Gideon and his family.
