24 Then Gideon said to them, "Let me make a request of you; each of you give me an earring he has taken as booty." (For the enemy had golden earrings, because they were Ishmaelites.) 25 "We will willingly give them," they answered. So they spread a garment, and each threw into it an earring he had taken as booty. 26 The weight of the golden earrings that he requested was one thousand seven hundred shekels of gold (apart from the crescents and the pendants and the purple garments worn by the kings of Midian, and the collars that were on the necks of their camels). 27 Gideon made an ephod of it and put it in his town, in Ophrah; and all Israel prostituted themselves to it there, and it became a snare to Gideon and to his family.

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!
