Matthew Poole and continuators on Matthew 21:9

9 And the multitudes that went before, and that followed, cryed, saying, Hosanna to the son of David, Blessed is he that cometh in the name of the Lord, Hosanna in the highest.

Mark saith, Ch. 11.7. And they brought the Colt to Iesus, and cast their Garments on him, and he sate upon him. And many spread their Garments in the way, and others cut down Branches of the Trees and strewed them in the way: And they that went before, and they that followed, Cryed, Saying, Hosanna! Blessed is he that cometh in the Name of the Lord. Blessed be the Kingdom of our Father David, that cometh in the Name of the Lord. Hosanna in the highest. Luke hath it yet with more Circumstances, Ch. 19.35, 36, 37, 38, 39, 40. And they brought him to Iesus, and they cast their Garments upon the Colt, and they set Iesus thereon: And as he went, they spread their Cloaths in the way: And when he was nigh, even now at the Descent of the Mount of Olives, the whole multitude, of the Disciples, began to Rejoyce, and Praise God with a loud Voice, for all the mighty Works they had seen, saying, Blessed be the King, that cometh in the Name of the Lord, Peace in Heaven, and Glory in the Highest. And some of the Pharisees from amongst the multitudes, said unto him. Master rebuke thy Disciples. And he answered and said unto them, If these should hold their Peace, the stones would immediately Cry out. Iohn also gives us some Account of this, Ch. 12.12, 13. On the next day much People that were come to the Feast, when they had heard that Iesus was coming to Ierusalem, took Branches of Palm Trees, and went forth to meet him, and Cryed, Hosanna: Blessed be the King of Israel, that cometh in the Name of the Lord. They bring the Ass, and the Colt to Iesus, who had no Saddle, no costly Furniture for him; they were glad to lay on the Asses back some of their Garments, and to set Christ upon the Colt. And in a kind of a natural Country Triumph, made up without any kind of Art, some threw their Cloths in his way, some cut down Boughs of Trees (Palm Trees saith Iohn) with these they bestrew the way. Christ at Bethany in his Journey, had done a Famous Miracle, raising up Lazarus from the Dead. Iohn saith, Ch. 12.18. the Fame of this, made many that were in Ierusalem, who were come thither against the Passover time (for Ioh. 12.1. it was but six Days before the Passover) go out to meet him, and joyned with those, who came along with him from Bethany, they Cryed all along as they came, Hosanna to the Son of David. Blessed is he that cometh in the Name of the Lord. Hosanna in the Highest. Blessed is the Kingdom of our Father David. Peace in Heaven, and Glory in the Highest. Many of these Expressions, seem to be taken out of Psal. 118.24, 25, 26. Their laying the Garments upon the Ass, and throwing them in the way, was a Custom they used towards Princes, as appears, not only by many Records out of profane Authors, but from 2 Kin. 9.13. where the like was done to Iehu, upon his being anointed King over Israel. For the Acclamations, they were also such as were usual to Princes: Whether Hosanna signifieth, Save now: Or, Help! We pray: Or, whether it was a Term by which they expressed their Desire of good Success, or Prosperity to the Person, to whom they apply'd it: Or, whether it was the Name of some Song used in their Festivals, or it signifies, Boughs, &c. is not much Material; they by this Acclamation, acknowledged him a King, the Son of David; they Blessed him, they wished him Peace, Honour and Glory. This was the Acclamation of the multitude, who doubtless had but a small, and imperfect knowledge of the Divine Nature of Christ, but yet looked on him, as the Son of David, as the Messiah. The Pharisees (some of which it seemeth had mixed themselves with this multitude, were troubled at the Acclamation, and (as Luke tells us) speak to Christ to rebuke them; but he answereth, If these should hold their Peace, the stones would immediately Cry out. It is a Proverbial Expression, the Sense of which is alone to be attended. The Sense is this: The time is come, set by my Father for the Publication of my Kingdom, and declaring what I am, and when Gods time is come, the thing must come to pass, by one mean or another: If these Children of Abraham should hold their Peace, God is able of these stones to raise up Children to Abraham, and they should do the same thing, publish me as the Son of David, the King in Zion.
