Tower of Shechem
TOWER OF SHECHEM
(mighdal shekhem): Mentioned only in Judges 9:46-49. It seems along with the Beth-millo and the Beth-el-berith to have comprised the three strongest parts of the fortification when Abimelech besieged the town. It was, however, abandoned by its defenders, who took refuge in the Beth-millo, in which they were slain.
