Catena Aurea on Luke 22:7–13: Origen

But I think that the man who meets the disciples as they enter into the city, carrying a pitcher of water, was some servant of a master of a house, carrying water in an earthen vessel either for washing or for drinking. And this I think is Moses conveying the spiritual doctrine in fleshly histories. But they who follow him not, do not celebrate the Passover with Jesus. Let us then ascend with the Lord united to us, to the upper part in which is the guestchamber, which is shewn by the understanding, that is, the goodman of the house, to every one of the disciples of Christ. But this upper room of our house must be large enough to receive Jesus the Word of God, who is not comprehended but by those who are greater in comprehension. And this chamber must be made ready by the goodman of the house, (that is, the understanding,) for the Son of God, and it must be cleaned, wholly purged of the filth of malice. The master of the house also must not be any common person having a known name. Hence He says mystically in Matthew, Go ye to such a one.
