Jerome : "Where the treasuries were lower on the upper levels because the porticoes that protruded from the lower and middle parts of the building supported them. These porticoes were narrow and did not have columns like the columns of the courtyards, so they protruded from the lower and middle parts of the building by fifty cubits." It follows: And their doors to the north, where the treasuries were in the lower and middle parts: because the porticoes which stood out from the lower and middle parts of the building supported them. For they were narrow, and did not have columns like the columns of the courts: therefore they stood out from the lower and middle parts by fifty cubits from the ground. What is joined: the doors of these, it is understood, (belong to) the exedrae or treasury rooms, about which there was discussion above. The treasuries were on the upper floors, that is, in the lower rooms. The upper rooms were ascended by Elijah and Elisha (1 Kings 17; 2 Kings 4); and the Lord, with the disciples, celebrated the Passover (Mark 14), and Tabitha, who was raised by the Apostle's faith and the merit of her virtues (Acts 9). These are the upper rooms, about which it is written in the psalm: He waters the mountains from his upper rooms (Psalms 104, 13). For unless a mountain is made, and rises to higher things, it will not be irrigated by the rains of the Lord, which for the diversity of merits are irrigated in the first, second, and third coenaculum. Even the storerooms themselves, that is, the treasuries of the Lord's treasures, are lower in the higher places. (Ephesians 3). However, the higher one is, the more one is humbled with the Apostle, saying: I am not worthy to be called an Apostle, because I persecuted the Church of God. (1 Corinthians 1:9). However, the treasure rooms themselves were located in the lower rooms, because they supported the porticoes that projected from the lower and middle parts of the building. And the reason why the treasure rooms were placed in the lower rooms and were lower was this: because the porticoes, which enjoyed the freedom of the air, supported and projected from the lower and middle parts of the building. In this way, the second floor of the building would be higher than the first floor, and the third floor would be higher than the second, so that as one ascended to higher levels, they would use a higher treasure room, which increased in humility, as the Lord says: 'If anyone wishes to be first, he shall be the last of all and the servant of all.' (Mark 9:35). For they were not carried by other columns, as we read in the columns of the atrium; but they protruded from the lower and middle parts of the ground by fifty cubits, as a sign of the remission of all debts. These, however, are the sad things of which it is commanded: Describe them in triple form, with counsel and knowledge, so that you may answer with words of truth those things that are proposed to you (Prov. 22:20-21). Therefore, the lower and outer parts need columns, but the higher and inner parts do not need the support of columns, that is, of external help. — Commentary on Ezekiel
