Megiddo; Megiddon

Boyd’s Bible Dictionary:

(crowded). A city in plain of Esdraelon (Josh. 12:21; 17:11; 2 Kings 23:29). Also the plain, or valley, itself and scene of Barak’s victory over Sisera, and of Josiah’s death (Judg. 4:6-17; 2 Chron. 35:20-24).

Concise Bible Dictionary:

City and valley on the borders of Issachar and Manasseh. It was conquered by Joshua (Josh. 12:21). Later it is mentioned among the cities from which Manasseh did not drive out the inhabitants; “the Canaanites would dwell in that land” (Josh. 17:11; Judg. 1:27). The rout of Sisera’s army was in this district; and at Megiddo Josiah fell when he rashly attacked Pharaoh-nechoh (Judg. 5:19; 1 Kings 4:12; 1 Kings 9:15; 2 Kings 9:27; 2 Kings 23:29-30; 1 Chron. 7:29; 2 Chron. 35:22; Zech. 12:11). See ARMAGEDDON. The city is identified by some with el Lejjun, 32° 35' N, 35° 10' E, but others prefer the ruins at el Mujedda, 32° 28' N, 35° 27' E. The valley is otherwise known as “the valley of Jezreel.” The WATERS of MEGIDDO probably refer to the copious springs found in that district.
