Judges 8:17-27

17 Then he tore down the tower of Penuel and killed the men of that city.
18 He asked Zebah and Zalmunna, "What kind of men did you kill at Tabor?" They answered, "They were like you. Each one looked like a king's son."
19 Gideon replied, "They were my brothers, my mother's sons. I solemnly swear, as the LORD lives, if you had let them live, I would not have to kill you now."
20 Then he told Jether, his firstborn son, "Get up and kill them!" But Jether didn't draw his sword. He was afraid because he was only a young man.
21 Zebah and Zalmunna said, "Get up and do it yourself! It's a man's job!" So Gideon got up and killed them. Then he took the half-moon ornaments that were on their camels' necks.
22 The men of Israel said to Gideon, "You, then your son, and then your grandson, must rule us. You rescued us from Midian."
23 Gideon replied, "I will not rule you nor will my son. The LORD will rule you."
24 Then Gideon said to them, "Do me a favor. Each of you give me the earrings from your loot." (Their enemies, the Ishmaelites, wore gold earrings.)
25 The men of Israel answered, "Yes, we'll give them to you." So they spread out a coat. Each man took the earrings from his loot and dropped them on it.
26 The gold earrings Gideon had asked for weighed 40 pounds. This did not include the half-moon ornaments, the earrings, the purple clothes worn by the kings of Midian, and the chains from their camels' necks.
27 Then Gideon used the gold to make an idol and placed it in his hometown, Ophrah. All Israel chased after it there as though it were a prostitute. It became a trap for Gideon and his family.
