Ps 121:4

“"For there the tribes went up" [Psalm 122:4]. We were asking whither he ascends who has fallen; for we said, it is the voice of a man who is ascending, of the Church rising. Can we tell whither it ascends? Whither it goes? Whither it is raised? "Thither," he says, "the tribes went up." Whither? To "partaking in the Same." But what are the tribes? Many know, many know not. For if we use the word "curies" in its proper sense, we understand nothing, save the "curies" which exist in each particular city, whence the terms "curiales" and "decuriones," that is, the citizens of a curia or a decuria; and you know that each city has such curies. But there are, or were at one time, curies of the people in those cities, and one city has many curies, as Rome has thirty-five curies of the people. These are called tribes. The people of Israel had twelve of these, according to the sons of Jacob.”

“There ascended the tribes For there in Shiloh the tribes ascended when they went up from Egypt, and the Tabernacle was established in its midst. the tribes of God Heb. יָ-הּ, which is testimony to Israel, for the heathens were talking about them when they left Egypt, and they would say about them that they were the offspring of adulterous unions. If the Egyptians ruled over their own bodies, surely [they ruled] over their wives. Said the Holy One, blessed be He, “I attest that they are the sons of their fathers.” He bestowed His name upon them: the Reubenites (הראובני), the Simeonites (השמעוני) (Num. 26). He added the letters of the name, one on this side and one on that side. The result is that this name יָ-הּ is testimony to Israel.”
