Genesis 49:11

I mean, since the ass is an unclean animal, hence he says, "Those unclean Gentiles will be introduced with such ease as if someone were to tether the foal to the stem of the vine, referring to the extraordinary degree of his authority and to the great responsiveness of the Gentiles." That is to say, its readiness to be tethered to the stem of the vine is a mark of the ass's gentleness. Now it was to the vine that Jesus compared his own teaching: "I am the true vine," he says, remember, "and my Father is the vinedresser."

This is appropriately and exclusively said about Christ. He that said, "I am the true vine" bound his foal to the vine. Therefore he binds his foal and his ass's foal to this vine. His foal is the people of the nations, onto whom certainly the burden of the law had never been imposed and among whom no one but he had ever held the first position. His ass's foal are those, who coming from the first people symbolized here by the she-ass, were elected for salvation and about whom the prophet says, "If the sons of Israel are like the sand of the sea, the rest shall be saved." After rejecting the she-ass who preferred to wear the yoke of the law in its infidelity, the foal born from it is elected, that is, a new people coming from the old one through faith is adopted and associated to the people of the nations. Therefore Christ is called "vine" because he has received the human nature, to which the Word of God binds his foal, that is, unites his people and associates it with that way of life that he followed in the flesh, so that the foal that has been bound may become with him son of God and coheir of Christ.

"Binding his foal to the vine." Here we understand "foal" as the sense itself (intelligence, reason) on account of the renewal of life: that same sense which elsewhere the Lord calls "child," when he says, "Truly I tell you, unless you change and become like children, you will never enter the kingdom of heaven." When one unites with the Lord and becomes a single spirit with him, he binds his foal to the vine by saying, "It is good for me to cleave close to God." "And his ass's foal to its branch." That branch or rather that tendril, as we have interpreted it above, can be understood as the subtle and flexible intelligence of knowledge. When the ass's foal, that is, the senses of the soul, are bound to it, they prevent the soul itself from falling.

"He shall wash his robe in wine and his garment in the blood of grapes." These words, on the basis of the historical account, will appear to signify a fertile land full of vineyards or, in a hyperbolic manner, the abundance of wine. But the mystical explanation will give them a nobler sense. Christ's robe washed in wine is interpreted with good reason as the church, which he himself has purified in his blood and is spotless and faultless. "You were not redeemed through silver and gold," the apostle says, "but through the precious blood of the only-begotten Son of God." And therefore in the wine of that blood, that is, in the bath of regeneration Christ washes the church. And we are buried with him through baptism in his death and in his blood.… But let us see how he will wash his garment in the blood of grapes. The garment appears to be a more intimate cloth, which is closer to the body than the robe. Those who, after they had been washed with the bath and had become his robe, reached the sacrament of the blood of grapes, that is, a more intimate and more secret mystery; they in a sense participate in his garment. In fact, the soul is washed in the blood of grapes, when it has begun to grasp the meaning of that sacrament. After perceiving and comprehending the virtue of the blood of the Word of God, the soul will become more receptive as it is purer. Each day it is washed in order to improve in its knowledge.

(Verse 11.) He ties his young donkey to the vine, and the colt of the donkey to the choice vine. In Hebrew it says, He ties his young donkey to the vine, and in Sorec, his donkey's colt to the choice vine: which colt of the donkey, that is, the Gentile people whom Jesus has taken over, that is, the Apostles' vineyard, who are from the Jews, he has joined together. And in Sorec, that is, the chosen vine, he has tied the donkey, over whom he has taken control, the Church gathered from the nations. And what he says, my son, he addresses to Judas himself, because Christ will do all of this. But it should also be known that where we read: Alligating to its vine its foal, can be read as 'its foal' in Hebrew, its city, with the same meaning demonstrated by other words in the Church, of which it is written elsewhere: A city that is set on a hill cannot be hidden (Matt. 5:15). And the streams of the river make the city of God glad (Psalm 46:5).

"He will wash his robe in wine." The good robe is the flesh of Christ, which has covered the sins of all people, taken up the offenses of all, concealed the misdeeds of all—the good robe which has clothed all people with the garment of rejoicing. He washed this robe in wine at his baptism in the Jordan, when the Holy Spirit came down like a dove and remained upon him. By this, it is indicated that the fullness of the Holy Spirit will be indivisible in him and will not depart. On this account also the Evangelist says, "The Lord Jesus, full of the Holy Spirit, returned from the Jordan." Therefore Jesus washed his robe, not to wash away his stain, for he had none, but to wash away the stain that was ours. Then Jacob continued, "and his mantle in the blood of the grape." This means that in the passion of his body he washed the nations with his blood. Truly the mantle represents the nations, as it is written, "As I live, says the Lord, unless I shall clothe myself with them all, as with a garment," and in another passage, "Like clothing you will change them, and they will be changed." And so with his own blood he cleansed not his own sins, for there were none, but the offenses that we committed. It was appropriate that Jacob spoke of a grape, because Christ hung on the wood like a grape. He is the vine, he is the grape; he is the vine because he cleaves to the wood and the grape because, when his side was opened by the soldier's lance, he sent forth water and blood. For thus John said that "there came out from him blood and water," water for baptism, blood for redemption. The water washed us, the blood redeemed us.

Binding his foal unto the vine, and his ass's colt unto the choice vine,.... Which may be understood either of the tribe of Judah, and signify that vines should grow in such plenty, and so large and strong, that a man might fasten his ass to one of them, and if it ate and destroyed it, it would give no great concern, since the country abounded with them; or they would be so full of clusters that a man might load an ass from one of them.
