Ezekiel 40:43

(Verse 35 and following) 'And he brought me to the gate that faced the north, and he measured it according to the higher measurements: its chamber, its facade, its vestibule, and its windows all around: it was fifty cubits long and twenty-five cubits wide. Its vestibule faced the outer court, and its palm tree engravings on its facade on both sides, and its staircase with eight steps.' And at each treasury there shall be a door in the gates (or fronts) of the doors: there they shall wash the holocaust.

Upon which they place the vessels in which the holocaust and victim are immolated. Whence it openly follows: Upon which they place the vessels in which the holocaust and victim are immolated. For what are the souls of the faithful, if not holy vessels that receive words of piety, so that from their minds a holocaust of life and prayer may be offered? Hence it is that Paul, when he was still unlearned in the calling of faith, because he had already received the words of the Lord and was full of heavenly grace, is called a vessel, when it is said: He is a vessel of election to me. Hence the prophet admonishes pastors and teachers, saying: Be cleansed, you who bear the vessels of the Lord. For they carry the vessels of the Lord as if upon a table, who by instructing support the life of the faithful, so that at some time they may lead them to the Lord for holocaust and sacrifice. But neither should this be regarded carelessly, that in these same vessels holocaust and victim are said to be offered. For a holocaust, as we also said above, is a victim, yet a victim is not always a holocaust, because when something is offered in part and retained in part, it is indeed a sacrifice, but it is not a holocaust. But truly in the great multitude of the faithful there are some who leave all things that are of the world, bestow all that they possess, reserve nothing for themselves, yearn from their inmost being for the eternal homeland, and slay themselves wholly in tears. These evidently are vessels upon the table, in which a holocaust is offered. And there are others who bear care for their own household, think of their children, and preserve an inheritance for them, who nevertheless, mindful of the eternal judgment, bestow mercy upon the poor, and give them food and clothing from whatever portion they have determined.

And their edges were of one palm, turned inward all around. There follows: And their edges were of one palm, turned inward all around. What does it mean that the borders of the tables are measured by a palm-span, except that in a palm-span the hand is stretched out, and the holy fathers and teachers preach those things in which the works of their hearers are stretched forth? For we stretch out the hand, as it were, when we extend our works. Therefore let every teacher speak, let him exercise the heart of his hearer, let him shake off the torpor of the idle. When he has stretched them toward good works, let him show that he has a palm-span on his lips. It must also be considered that in a palm-span the greatest and smallest fingers are stretched out. What is signified by the greater and smaller finger, except the greatest and smallest action? Therefore let the tables have a palm-span on their borders, so that in the preaching of their teachers one may do great works, yet not omit to do even the smallest things. Let one be so attentive to the smallest things that one is not sluggish in doing the greater. Hence Truth says through the Gospel: "Woe to you, scribes and Pharisees, hypocrites, because you tithe mint and dill and cumin, and have neglected the weightier matters of the law: judgment, mercy, and faith; these things you ought to have done, and not to have omitted those." For through judgment, mercy, and faith, the greater finger of action is shown. But through mint, dill, and cumin, without doubt the smallest finger is represented. Therefore these things ought to have been done, and those not omitted, because if we wish to measure our work by a palm-span, it is necessary that the smallest finger be stretched out in such a way that the greater finger is not drawn back.

And their edges were of one palm. But well, when the edges of the tables are measured, and the measure is said to be a palm, "one" is added, so that from the preaching of the teachers, just as unity is held in faith, so also unity of minds may be preserved in work, lest through the good work which one does, another break forth into the evil of discord. For we ought to do good works in such a way that through these also we preserve unanimity with those with whom we live, insofar as we rightly can—that is, not abandoning what we do, but forestalling with good persuasions the evil of discord that we fear. Thus Paul, preserving the unity of the palm in his works, was forbidding discord from being generated, when he saw that the Corinthians now wanted to receive back a certain one who had fallen and been cast out from the Church, saying: "If you have forgiven anyone anything, so have I. For what I have forgiven, if I have forgiven anything, was for your sake in the person of Christ, lest we be outwitted by Satan." Who indeed is accustomed to generate evils from goods, and to drag what is done in charity toward discord. Whence he also immediately added concerning him, saying: "For we are not ignorant of his designs." But a teacher who through the good things he preaches forms right action in his hearers, if he does not bind the minds of those working to unanimity, has a palm in the edges, but does not have that unity of the palm which has been spoken of.

Turned inward all around. It must be carefully considered what is said, that the lips of these same tables are turned inward. For the lips of the tables are turned inward when teachers recall to their conscience by silent thought what they say, when they subtly examine themselves whether they do what they speak. Rightly, moreover, when the lips of the tables are said to be turned inward, it is also added "all around," so that they do not consider themselves in just one part and neglect to weigh themselves in another, but inspect themselves everywhere, and, insofar as they are able, strive to fulfill in deed each thing they teach, lest if those who preach pretend not to do good, they become destroyers of themselves while cultivating others. O teacher, behold you are now a table, you now carry vessels, you now sustain in faithful vessels the weight of holocaust and sacrifice, but turn the lip inward, that is, recall your speech to your heart. Hear what you say, do what you preach. For if you neglect to fulfill what you preach, you sow a harvest for others, and you yourself fast from participation in the grain. Hence it is written: "Whose harvest the hungry shall eat." For the hungry eats the harvest of the teacher who speaks good things but does not do them, because he who hungers for the bread of justice performs the commands he hears, and he himself who labored in sowing has no fruit. Hence Solomon says: "The sluggard hides his hand under his armpit and does not bring it to his mouth." No one is so lazy as to think it labor to bring his hand back to his mouth even for eating. But the sluggard does not bring his hand to his mouth, who does not want to do what he says. […]
