Zechariah 12:8

And he that is feeble, &c.— And he who had fallen among them—shall be as David,—when he seemed to have fallen before Saul, and was compelled to hide himself in mountains and caves. The Jews are called the house of David, as the Messiah himself is called David. See Houbigant. Calmet says, it appears that the prophet would point out the birth of Christ by these words, The house of David shall be, &c. and would convince the Israelites that henceforward this ancient and illustrious house must derive its splendour and glory, not from its empire over the nation, but from its own virtue, and from its fidelity to the Lord. Indeed the house of David never did reascend the throne; but was well recompensed, notwithstanding, by the honour that it enjoyed of producing the blessed Jesus. Angel or messenger is, as we have before observed, one of the titles of the Messiah. The terms are varied in Micah 2:13 where it is said, The Breaker, or Redeemer (as it should be rendered), is gone before them: their king is past, even the Lord, &c. to signify by these synonymous expressions, that one and the same person is intended by them all; even the Messiah, as the Jews themselves say, who is the angel of the Lord. See Chandler's Defence, p. 63.
