Psalms 69:23

That cluster of grapes that was brought from the land of promise on a lever across the shoulders of two men further prefigured Christ. Just as it was hung on the wood and brought by the services of those two men, so Christ, who came from the flesh of a virgin as from the promised land, was between both Testaments, between the two peoples of the Jews and Gentiles, and was hung on the wood of the cross. Now of the two men who walked beneath the burden of that cluster of grapes, the first one signified the Jewish people of whom it is said, "Let their eyes grow dim so that they cannot see, and keep their backs always feeble." However, the man who came after prefigured our people, that is, the Gentiles who believe and keep Christ before their eyes. They intend always to follow him as a servant does his master or a disciple his teacher, as the Lord says in the Gospel: "If anyone wishes to come after me, let him deny himself, and take up his cross and follow me." Moreover, this cluster of grapes poured forth the wine of his blood that was pressed out under the weight of the cross for our salvation and gave the church that chalice of his passion to drink. For this reason it was said to the apostles at the time of the birth of the church, "They are full of new wine."

"Let the table of them be made in their own presence for a trap" [Psalm 69:23]. Like the trap which for Me they set, in giving Me such a draught, let such a trap be for them. Why then, "in their own presence"? "Let the table of them be made for a trap," would have been sufficient. They are such as know their iniquity, and in it most obstinately do persevere: in their own presence there is made a trap for them. These are they that, being too destructive, "go down into Hell alive." Lastly, of persecutors what has been said? Except that the Lord were in us, perchance alive they had swallowed us up. What is alive? Consenting to them, and knowing that we ought not to consent to them. Therefore in their own presence there is made a trap, and they are not amended. Even though in their own presence there is a trap, let them not fall into it. Behold they know the trap, and thrust out foot, and bow their necks to be caught. How much better were it to turn away from the trap, to acknowledge sin, to condemn error, to be rid of bitterness, to pass over into the Body of Christ, to seek the Lord's glory! But so much prevails presumption of mind, that even in their own presence the trap is, and they fall into it. "Let the eyes of them be darkened, that they see not," follows here: that whereas without benefit they have seen, it may chance to them even not to see. "Let the table of them," therefore, "be made in their own presence for a trap." It is not from one wishing, but from one prophesying: not in order that it may come to pass, but because it will come to pass. This we have often remarked, and you ought to remember it: lest that which the prescient mind says in the Spirit of God, it should seem with ill will to imprecate....Let it then be done to them, "both for a requital and for a stumbling-block." And is this by any means unjust? It is just. Why? For it is "for a requital." For not anything would happen to them, which was not owed. "For a requital" it is done, "and for a stumbling-block:" for they are themselves a stumbling-block to themselves.
