Man-killer, or sacrifice, one of the two kings who led the vast host of the Midianites who invaded the land of Israel, and over whom Gideon gained a great and decisive victory (Judg. 8). Zebah and Zalmunna had succeeded in escaping across the Jordan with a remnant of the Midianite host, but were overtaken at Karkor, probably in the Hauran, and routed by Gideon. The kings were taken alive and brought back across the Jordan; and confessing that they had personally taken part in the slaughter of Gideon's brothers, they were put to death (comp. 1 Sam. 12:11; Isa. 10:26; Ps. 83:11).
