Edar

tower of the flock, a tower between Bethlehem and Hebron, near which Jacob first halted after leaving Bethlehem (Gen 35:21). In (Mic 4:8) the word is rendered "tower of the flock" (marg., "Edar"), and is used as a designation of Bethlehem, which figuratively represents the royal line of David as sprung from Bethlehem.
