And the plans for all that he had by the Spirit, of the courts of the house of the LORD, and of all the chambers round about, of the treasuries of the house of God, and of the treasuries of the dedicated things:

It is to be noted, of course, that the thirty cubits of height spoken of above reached to the middle story; from there on to the third story another thirty cubits were added until the portico that was around the temple on the south and north and east reached the roof, as we learn from Josephus’s account; from there to the top of the temple roof was another sixty cubits, and so the total height of the house according to the book of Paralipomenon amounted to 120 cubits. Also the portico that was in front of the temple to the east, according to the account of the aforesaid volume, was the same number of cubits in height. That is, the porticoes around the temple of which we have just spoken, this book calls treasuries and inner chambers. David, it says, “gave his son Solomon a plan of the portico, and of the temple, and of the treasuries, and of the upper room, and of the inner chambers and of the room for the mercy seat”; here too he refers to the outer houses that were outside the courtyard of the priests surrounding the temple, when he adds, “As also of all the courts that he had in mind, and of the surrounding chambers for the treasuries of the house of the Lord and for the treasuries for dedicated objects.” The fact that the entire height of the temple was 120 cubits refers to the same mystery as when the primitive church in Jerusalem after the passion and resurrection and ascension of the Lord into heaven received the grace of the Holy Spirit in the same number of men. For fifteen, which is the sum of seven and eight, is sometimes taken to signify the life that is now lived in the sabbath rest of the souls of the faithful but will be brought to perfection at the end of the world by the resurrection of their immortal bodies. Now this fifteen arranged in a triangle, that is, numbered with all its parts, makes 120. Hence by the number 120 the great happiness of the elect in the life to come is aptly represented, and by it the third story of the Lord’s house is aptly completed because after the present hardships of the faithful and after their souls receive their rest in the life to come, the complete happiness of the whole church will be achieved in the glory of the resurrection. To this mystery likewise refers, as we have said, the fact that the Lord on rising from the dead and ascending into heaven sent to this number of men in tongues of fire the Holy Spirit, who enabled them, though differing from each other on account of the diversity of their languages, suddenly to speak in his praise in a common tongue by giving them a knowledge of all languages. For the church too in its own turn rising from the dead and ascending to heaven in incorruptible flesh will be fully and perfectly enlightened by the gift of the Holy Spirit when, according to the promise of the apostle, “God” will be “all in all.” Then there will be complete unity of languages universally for the preaching of the wonderful works of God because all join with one mind and voice in praising the glory of the divine majesty that they see before them. - "On the Temple 1.8.2"
