24 Then Gideon said, "But I do have one request. Give me, each of you, an earring that you took as plunder." Ishmaelites wore gold earrings, and the men all had their pockets full of them. 25 They said, "Of course. They're yours!" 26 The gold earrings that Gideon had asked for weighed about forty-three pounds - and that didn't include the crescents and pendants, the purple robes worn by the Midianite kings, and the ornaments hung around the necks of their camels. 27 Gideon made the gold into a sacred ephod and put it on display in his hometown, Ophrah. All Israel prostituted itself there. Gideon and his family, too, were seduced by it.

Commentary on Judges 8:22-28
(Read Judges 8:22-28)
Gideon refused the government the people offered him. No good man can be pleased with any honour done to himself, which belongs only to God. Gideon thought to keep up the remembrance of this victory by an ephod, made of the choicest of the spoils. But probably this ephod had, as usual, a teraphim annexed to it, and Gideon intended this for an oracle to be consulted. Many are led into false ways by one false step of a good man. It became a snare to Gideon himself, and it proved the ruin of the family. How soon will ornaments which feed the lust of the eye, and form the pride of life, as well as tend to the indulgences of the flesh, bring shame on those who are fond of them!
