Tower Of Edar
Fausset's Bible Dictionary [1]
Genesis 35:21. Jacob's first halting place between Bethlehem and Hebron was "beyond" this. The name means "a flock" or "drove." The tower was to watch the flock against wild beasts or robbers. Jewish tradition made it the destined birthplace of Messiah. Jerome saw in it the foreshadowing of the announcement of His birth to the "shepherds." Probably the Tower of Edar answers to the present Khirbet Sir El Ghanem , "the ruin of the sheepfold," which however contains Christian remains, arches, cisterns, tombs, etc.
Morrish Bible Dictionary [2]
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.
