Oreb
Judges 7:25
And they took two princes of the Midianites, Oreb and Zeeb; and they slew Oreb upon the rock Oreb, and Zeeb they slew at the winepress of Zeeb, and pursued Midian, and brought the heads of Oreb and Zeeb to Gideon on the other side Jordan.
Zebah
Judges 8:12-21
12
And when Zebah and Zalmunna fled, he pursued after them, and took the two kings of Midian, Zebah and Zalmunna, and discomfited all the host.
13
And Gideon the son of Joash returned from battle before the sun was up,
14
And caught a young man of the men of Succoth, and enquired of him: and he described unto him the princes of Succoth, and the elders thereof, even threescore and seventeen men.
15
And he came unto the men of Succoth, and said, Behold Zebah and Zalmunna, with whom ye did upbraid me, saying, Are the hands of Zebah and Zalmunna now in thine hand, that we should give bread unto thy men that are weary?
16
And he took the elders of the city, and thorns of the wilderness and briers, and with them he taught the men of Succoth.
17
And he beat down the tower of Penuel, and slew the men of the city.
18
Then said he unto Zebah and Zalmunna, What manner of men were they whom ye slew at Tabor? And they answered, As thou art, so were they; each one resembled the children of a king.
19
And he said, They were my brethren, even the sons of my mother: as the LORD liveth, if ye had saved them alive, I would not slay you.
20
And he said unto Jether his firstborn, Up, and slay them. But the youth drew not his sword: for he feared, because he was yet a youth.
21
Then Zebah and Zalmunna said, Rise thou, and fall upon us: for as the man is, so is his strength. And Gideon arose, and slew Zebah and Zalmunna, and took away the ornaments that were on their camels' necks.
