Jerome : (Vers. 10, 11.) And you gathered the waters of the lower pool, and you counted the houses of Jerusalem, and you destroyed houses to fortify the wall. And you made a reservoir between the two walls, and the water of the Old Pool. And you did not look to the One who made it, and you did not see the One who fashioned it from afar. It tells how they prepared the city for siege, and transferred the waters of the lower pool to the upper fortification, and after destroying the houses, they built walls, and through each family, they counted the amount of water that each house should receive, and they made a cistern between the two walls, and restored the old pool to preserve the water. And they did not call upon the help of God, who is the creator of the city and the Lord of the pool; as if God had said in other words: You trusted in man and not in God, who is the maker of man. Certain people, according to a mystical understanding, understand the old pool to be a shadow of the Law, and between two walls, namely the new and old Testament, they see a lake built by the Pharisees' traditions and commands, which cannot contain water: and they did not look to the Son of God, nor did they believe in His presence, whom they had never seen before, because they have always been incredulous to God's precepts. — Commentary on Isaiah Jerome : (Vers. 10, 11.) And you gathered the waters of the lower pool, and you numbered the houses of Jerusalem, and you destroyed houses to build a wall. And you made a reservoir between two walls, and the water of the old pool. And you did not look to Him who made it, and the worker of it from afar you did not see. LXX: And they turned the water of the old pool into the city, and they destroyed the houses of Jerusalem to strengthen the city wall. And you made water between two walls within the old pool, and you did not look to Him who made it from the beginning, and you did not see its creator. You who know the divisions of the city of David, that is, the Church, will see or have seen, which have multiplied throughout the world; you who have gathered the waters of your pool and your doctrine, not of the higher, but of the lower, and have counted the houses of Jerusalem, whether you have destroyed them to fortify your wall, you have not dug wells that would have had life-giving and eternal water, but broken cisterns that cannot hold water. And you have made them between the two walls of the old and new covenant, and you have neglected the water of the old pool, and you have not considered the giver of the law, God, and you have completely neglected the operator of the world. This is according to the Hebrew. Moreover, according to the Septuagint, the heretics considered themselves many, and with this confidence, they turned the teaching of the old Testament away from the city of God, which is the Church, and destroyed the houses of Jerusalem, in order to build meeting places of the wicked; and while they reject the old Testament, they have not followed the new, because the new is confirmed by the testimonies of the old Testament. Therefore, between the two walls of the old and the new, they have made for themselves new waters, which they think are interior and contain greater mysteries than those contained in the old Testament; and they have not respected God, who is the creator of the old Testament, and they did not even want to see his maker from afar. — Commentary on Isaiah
