25 And they gave answer, We will gladly give them. So they put down a robe, every man dropping into it the ear-rings he had taken. 26 The weight of the gold ear-rings which he got from them was one thousand, seven hundred shekels of gold; in addition to the moon-ornaments and jewels and the purple robes which were on the kings of Midian, and the chains on their camels' necks. 27 And Gideon made an ephod from them and put it up in his town Ophrah; and all Israel went after it there and were false to the Lord; and it became a cause of sin to Gideon and his house.

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!
