Rejoice greatly, O daughter of Zion; shout, O daughter of Jerusalem: behold, thy King cometh unto thee: he is just, and having salvation; lowly, and riding upon an ass, and upon a colt the foal of an ass.   Zech 9:9

     The narrowness and littleness of the mind of fallen man are sufficiently conspicuous in the idea he forms of magnificence and grandeur.  The pageantry and parade of a Roman triumph, or of an eastern monarch, as described in history, exhibit him to us in what he himself accounts his best estate.  If you suppose him seated in an imperial carriage, arrayed in splendid apparel, wearing a crown or tiara ornamented with jewels, preceded and followed by a long train of guards and attendants, surrounded by the unmeaning acclamations of ignorant multitudes, you see the poor worm at the summit of his happiness.  He has no conception of any thing greater than this.  And the spectators are generally of the same mind.  They admire, and they envy, his lot; and there is hardly a person in the crowds around him, but would be very glad to take his place, were it practicable.....
     How different was Messiah's entry into Jerusalem foretold in this prophecy, the accomplishment of which we read in the evangelists!  And how differently was he affected by the objects around him!  He poured contempt upon the phantom of human glory.  This King of kings and Lord of lords was meek and lowly, riding upon an ass's colt,  Luke 19:3-38.  And though a secret divine influence constrained the multitude to acknowledge his character, and, with some accommodation to the customs of the times, to strew their garments in the way, as they proclaimed the King who came in the name of Jehovah; yet he appeared unmoved by their applause.....
.....In the course of his ministry he appeared and was treated as a poor man, he had no certain dwelling-place, he submitted to receive supplies for his support from the contributions of a few of his followers, for the most of them were poor like himself.  And though he wrought many wonderful works for the relief of the necessitous and miserable, he admitted no alteration in his own external state, but was content to be poor and despised, for our sakes, to the end of his life.  I think the only occasion on which he permitted a public acknowledgment of his person and character, was when he fulfilled this prophecy.  And still he was the same meek and lowly Saviour.  As his kingdom was not of this world, neither were there any marks of human grandeur in his procession.  He approached Jerusalem, attended, indeed, by a concourse of people, but riding upon an ass, and weeping for his enemies.....
