This occurs only in Genesis 35:21 , and signifies 'Tower of the flock.' Probably a tower built by the shepherds for the protection of their flocks. It was apparently a little south of Bethlehem. Jacob halted there with his flocks. The expression 'tower of the flock' occurs in Micah 4:8 (Edar in the margin ) as the stronghold of the daughter of Zion.
