'Slain' in the Bible

Indeed, the people will rise up like a lioness, and like a lion raises himself up; they will not lie down until they eat their prey, and drink the blood of the slain."

They killed the kings of Midian in addition to those slain -- Evi, Rekem, Zur, Hur, and Reba -- five Midianite kings. They also killed Balaam son of Beor with the sword.
