John 12:15

Zechariah gave this prophecy after the return from Babylon toward the conclusion of prophecy. But there is no record of a Jewish king since that time, such as the prophecy predicts, except our Lord and Savior Jesus Christ, in whom this prediction was fulfilled.… But what was his riding on a donkey meant to show but the lowly and humble manner that marked his first coming?

"Rejoice greatly, daughter of Zion"? Because all their kings had for the most part been an unjust and covetous kind of men, and had given them over to their enemies, and had perverted the people, and made them subject to their foes; "Be of good courage," It saith, "this is not such an one, but meek and gentle"; as is shown by the ass, for He entered not with an army in His train, but having an ass alone.

And this He did, figuring one prophecy and fulfilling another; and the same act was the beginning of the one and the end of the other. For the, "Rejoice, for thy King cometh unto thee meek," belonged to Him as fulfilling a prophecy, but the sitting upon an ass was the act of one prefiguring a future event, that He was about to have the impure race of the Gentiles subject to Him.

But how say the others, that He sent disciples, and said, "Loose the ass and the colt," while John saith nothing of the kind, but that "having found a young ass, He sat upon it"? Because it is likely that both circumstances took place, and that He after the ass was loosed, while the disciples were bringing it, found the colt, and sat upon it.

(Tr. li. 5) John relates the matter briefly, the other Evangelists are more full. The ass, we read in them, was the foal of an ass on which no man had sat: i. e. the Gentile world, who had not received our Lord. The other ass, which was brought, (not the foal, for there were two,) is the believing Jew.

(Tr. li) This act of our Lord's is pointed to in the Prophets, though the malignant rulers of the Jews did not see in it any fulfilment of prophecy: As it is written, Fear not, daughter of Sion, behold thy King cometh sitting on an ass's colt. Yea, in that nation though reprobate, though blind, there remained still the daughter of Sion; even Jerusalem. To her it is said, Fear not, acknowledge Him whom thou praisest, and tremble not when He suffers. That blood it is which shall wipe away thy sins, and redeem thy life.

Jesus, then, "found a young ass, and sat thereon; as it is written, Fear not, daughter of Zion: behold, thy King cometh, sitting on an ass's colt." Among that people, then, was the daughter of Zion to be found; for Zion is the same as Jerusalem. Among that very people, I say, reprobate and blind as they were, was the daughter of Zion, to whom it was said, "Fear not, daughter of Zion: behold, thy King cometh, sitting on an ass's colt." This daughter of Zion, who was thus divinely addressed, was amongst those sheep that were hearing the Shepherd's voice, and in that multitude which was celebrating the Lord's coming with such religious zeal, and accompanying Him in such warlike array. To her was it said, "Fear not:" acknowledge Him whom thou art now extolling, and give not way to fear when He comes to suffering; for by the shedding of His blood is thy guilt to be blotted out, and thy life restored. But by the ass's colt, on which no man had ever sat (for so it is found recorded in the other evangelists), we are to understand the Gentile nations which had not received the law of the Lord; by the ass, on the other hand (for both animals were brought to the Lord), that people of His which came of the nation of Israel, and was already so far subdued as to recognize its Master's crib.

In this circumstance He was also fulfilling the prophecy of Zechariah, who said: "Fear not, daughter of Zion! Behold, your King comes to you, sitting on a young donkey" (Zech. 9:9). Since the kings of Jerusalem were, for the most part, unjust and greedy, the prophet says: "Fear not, daughter of Zion! The King of whom I foretell to you is not such, but is meek and humble-minded, and not at all proud." This is evident also from the fact that He came sitting on a donkey. For He entered not accompanied by an army, but rode on a single donkey.
The Lord's sitting upon the donkey was also a figure of things to come. This animal, unclean according to the law, was a figure of the unclean nation of the gentiles, upon which Jesus, the Word of God, sits, subjecting to Himself this disobedient and rough new people, like a donkey, whom He also leads up to the true Jerusalem after they have become tame and obedient to Him. For did not the Lord take up to heaven with Himself those gentiles who became His people and submitted to the preaching of the Gospel?

When the Evangelist says, as it is written, Fear not, daughter of Zion! he cites the prophesy which was written in Zechariah (9:9). First, he reassures them; secondly, he promises a kingly majesty; and thirdly, he adds the benefit which the king will bring.

He reassures them when he says, Fear not, daughter of Zion. Zion was the fortress in Jerusalem where the king lived. The daughter of Zion, therefore, would be the people of Jerusalem and of Judea who were subject to the king of Jerusalem. Thus the Jews are being told, Fear not, because the Lord is your defender: "Who are you that you are afraid of man who dies, of the son of man who is made like grass?" (Is 51:12); "The Lord is the defender of my life; of whom shall I be afraid?" (Ps 27:1). Here the Evangelist is driving out their worldly and servile fear.

He promises them a kingly majesty, saying, behold, your king is coming: "For to us a son is given" (Is 9:6); "Upon the throne of David, and over his kingdom" (9:7). He says, your king, that means, taking flesh from you, for "It is not with angels that he is concerned, but with the descendants of Abraham" (Heb 2:16). Again, your king, that is, for your benefit. Thus he adds, is coming, to you: "Would that even today you knew the things that make for peace! But now they are hid from your eyes" (Lk 19:42). But when they resisted, they hindered their own good.

The king comes to you, I say, not to harm you, but to set you free; thus he adds, sitting on an ass's colt! This signifies the mercy of the king, which is most welcome to his subjects: "His throne is upheld by mercy" (Prv 20:28). This is just the opposite to "A king's wrath is like the growling of a lion" (Prv 19:12). He is saying in effect: He is not coming as a haughty king - which would make him hateful - but with gentleness: "If they make you master of the feast, do not exalt yourself" (Sir 32:1). Therefore, have no fear that the king will oppress you. Now the Old Law was given in fear, because the Law produced slaves. This phrase also signifies the power of the king, because by coming with humility and in weakness he attracted the entire world: "The weakness of God is stronger than men" (1 Cor 1:25).
