Charles Ellicott Commentary 1 Kings 4:12

"Baana the son of Ahilud, in Taanach and Megiddo, and all Beth-shean which is beside Zarethan, beneath Jezreel, from Beth-shean to Abel-meholah, as far as beyond Jokmeam;" — 1 Kings 4:12 (ASV)

The fifth division must have been large and important, including much of the great plain of Esdraelon or Jezreel, the garden and battlefield of Northern Palestine, and extending to the Jordan valley. Taanach, Megiddo, and Beth-shean are all named as Canaanite cities not taken by Manasseh, but made tributary (Joshua 17:11; Judges 1:27). Taanach and Megiddo are referred to in the song of Deborah (Judges 5:19). Megiddo is the place of the death of Ahaziah (2 Kings 9:27) and the fall of Josiah (2 Kings 23:29).

Beth-shean is the city in which the body of Saul was exposed in triumph (1 Samuel 31:12). Abel-meholah, the birthplace of Elisha (1 Kings 19:16), lies south of Beth-shean, and is mentioned in the record of the rout of the Midianites by Gideon (Judges 7:22). Jokmeam (for such is the right reading) is a Levitical city in Ephraim (1 Chronicles 6:68), apparently called Kibzaim in Joshua 21:22, and must have been an outlying part of this division.
