8. tower of the flock--following up the metaphor of sheep (see on Mic 4:6). Jerusalem is called the "tower," from which the King and Shepherd observes and guards His flock: both the spiritual Jerusalem, the Church now whose tower-like elevation is that of doctrine and practice (So 4:4, "Thy neck is like the tower of David"), and the literal hereafter (Jer 3:17). In large pastures it was usual to erect a high wooden tower, so as to oversee the flock. JEROME takes the Hebrew for "flock," Eder or Edar, as a proper name, namely, a village near Beth-lehem, for which it is put, Beth-lehem being taken to represent the royal stock of David (Mic 5:2; compare Ge 35:21). But the explanatory words, "the stronghold of the daughter of Zion," confirm English Version.
      stronghold--Hebrew, "Ophel"; an impregnable height on Mount Zion (2Ch 27:3; 33:14; Ne 3:26, 27).
      unto thee shall . . . come . . . the first dominion--namely, the dominion formerly exercised by thee shall come back to thee.
      kingdom shall come to the daughter of Jerusalem--rather, "the kingdom of the daughter of Jerusalem shall come (again)"; such as it was under David, before its being weakened by the secession of the ten tribes.
