1 Samuel 6:8

And you will take the Ark of the Lord and place it on the cart, etc. Place the more secret parts of the heavenly mysteries, imbued with the new commandment of Christ, upon it, and also set forth for all together as an example to be observed and followed, in such a way that the Church, adorned with both the mysteries of faith and examples of virtues, may be sent to seek the remnants of the Israelite people, and never let your mind's eyes turn away from observing its steps.

11. Moreover, it is commanded that the golden vessels, which were rendered to the ark as a guilt offering, be placed at its side. For he calls "golden vessels" what he mentioned above, saying: "You shall make likenesses of your tumors and of your mice." In these vessels, as we had said, the memory of sins and temptations was signified. What does it mean, then, that above he declared them to be likenesses of tumors and mice, but now has called them golden vessels? But there the discussion concerned what had to be paid to the ark for sin, whereas here it concerns the sending away of the ark. What does it mean, then, that these same things are expressed by a more honorable name, except that sins which have not been cleansed by the tears of repentance must be viewed more attentively in their deformity and lamented, while those which have already been washed away by great weeping are not to be gazed upon more attentively or in their deformity, but are to be thought upon from time to time with an estimation of humility? For in the mind of the penitent who grieves bitterly, there is, as it were, a likeness of tumors and mice: when, so that he may mourn more attentively, he sees the accumulated mass of sin which he heaps before the eyes of his mind. But when, already somewhat secure about the remission of his sins through great and prolonged weeping, he has begun to hasten toward the heavenly homeland by the course of a great conversion, he now beholds, as it were, golden vessels: because he sees his sins not as things by which he saw himself bound, but as things which he may devote to the praises of almighty God. And rightly are those same vessels placed in a box at the side of the ark. For if the ark signifies the secret of divine knowledge, the vessels hang at its side because, while the height of divine knowledge elevates the mind, our past weaknesses must be recalled to memory for the sake of the virtue of humility. They are not, therefore, to be placed before the ark, lest, while we gaze upon our weaknesses too immoderately, we become unable to be raised up to heavenly things. It is clear, then, that they hang from the side: so that we may both freely behold heavenly things and, when it is fitting, recall the eyes of our mind to our own weaknesses. 12. But what does it mean that they are commanded: "And let it go, that it may depart"? The ark is let go when…
