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.
