Zechariah 9:9 - Matthew Poole's English Annotations on the Holy Bible

Rejoice greatly: the prophet calls for such a joy as expresseth itself in outward gesture, as indeed the daughters of Zion did in their hosannas, when this had its accomplishment. Daughter of Zion; Jerusalem's inhabitants, or the church. Shout; proclaim aloud your joy at the news I now tell you. Before it was daughter of Zion, now it is daughter of Jerusalem, both the church and state among the Jews had great cause to triumph at this. Thy King; the Redeemer, expected, promised Messiah, Son of David, the only restorer of your lapsed state. Cometh unto thee; Christ cometh to thee, to redeem and save thee; he cometh for thee, as well as to time. He is just; the righteous One, who cometh to fulfil all righteousness, and to be our righteousness. Having salvation; designs to save, and hath that in his eye, that he can save, it is in his power; he can save us as he did save himself, by raising himself from the dead. Lowly; low and mean of state, and meek or lowly of mind. Riding upon an ass; a beast of no state or price, an emblem of his outward state. And upon a colt the foal of an ass: in this some footsteps of sovereignty appeared in the colt's taking and bearing him quietly, Luke 19:35.
