Luke 19:33

And the prophecy, "He shall be the expectation of the nations," signified that there would be some of all nations who should look for Him to come again. And this indeed you can see for yourselves, and be convinced of by fact. For of all races of men there are some who look for Him who was crucified in Judaea, and after whose crucifixion the land was straightway surrendered to you as spoil of war. And the prophecy, "binding His foal to the vine, and washing His robe in the blood of the grape," was a significant symbol of the things that were to happen to Christ, and of what He was to do. For the foal of an ass stood bound to a vine at the entrance of a village, and He ordered His acquaintances to bring it to Him then; and when it was brought, He mounted and sat upon it, and entered Jerusalem, where was the vast temple of the Jews which was afterwards destroyed by you.

What then was the sign? He sat on a colt, as we have just heard the blessed Evangelist clearly telling us. Perhaps someone will say, "When he traveled all Judea—for he taught in their synagogues and added the working of miracles to his words—he did not ask for an animal on which to ride. When Christ could have purchased one, he would not, although he often was wearied by his long journeys on the way. When passing through Samaria, he was wearied with his journey, as it is written. Who can make us believe that when he was going from the Mount of Olives to Jerusalem, places separated from one another by so short an interval, that he would require a colt? Since the mother accompanied the colt, why did he not take the mother instead of choosing the colt? The donkey that bore the colt was brought to him also. We learn this from the words of Matthew, who says that he sent the disciples to a village opposite them. He said to them, "You will find a donkey tied and a colt with her. Untie and bring them to me." "They brought," it says, "the donkey and the colt with her." We must consider, therefore, what are the explanations and the benefits that we derive from this occurrence and how we make Christ riding on the colt a type of the calling of the Gentiles. The colt of a donkey is mounted on which none has sat, because no one before Christ called the peoples of the nations to the church.

They who had tied the ass are struck dumb, because of the greatness of His mighty power, and are unable to resist the words of the Saviour; for "the Lord" is a name of majesty, and as a King was He about to come in the sight of all the people.

And as they were loosing the colt, its owners said to them: Why are you loosing the colt? For it had many owners, being not devoted to one doctrine and superstition, but wretchedly carried off to various and diverse errors of idols at the whim …

Second, as regards the obedience of the disciples carrying out the command, it is added: And as they were loosing the colt, the owners thereof said to them: Why do you loose the colt? by the handling of another's property; and they are called several …
