'Heads' in the Bible

They captured two Midianite leaders, Oreb and Zeeb. While they were pursuing the Midianites, they executed Oreb at Oreb's Rock and Zeeb at Zeeb's Winepress, and then they carried the heads of Oreb and Zeeb to Gideon from the east bank of the Jordan River.

Midian remained subjugated to the Israelis, and they didn't so much as raise their heads anymore, so the land was peaceful for 40 years during the lifetime of Gideon.
