Judges 8:19-29

19 And he said, They were my brothers, my mother's sons: by the life of the Lord, if you had kept them safe, I would not put you to death.
20 Then he said to Jether, his oldest son, Up! Put them to death. But the boy did not take out his sword, fearing because he was still a boy.
21 Then Zebah and Zalmunna said, Up! Put an end to us yourself: for you have a man's strength. Then Gideon got up and put Zebah and Zalmunna to death and took the ornaments which were on their camels' necks.
22 Then the men of Israel said to Gideon, Be our ruler, you and your son and your son's son after him; for you have been our saviour from the hands of Midian.
23 But Gideon said to them, I will not be a ruler over you, and my son will not be a ruler over you: it is the Lord who will be ruler over you.
24 Then Gideon said to them, I have a request to make to you; let every man give me the ear-rings he has taken. (For they had gold ear-rings, because they were Ishmaelites.)
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.
28 So Midian was broken before the children of Israel and the Midianites never got back their strength. And the land had peace for forty years, in the days of Gideon.
29 And Jerubbaal, the son of Joash, went back to his house and was living there.
