George Leo Haydock, on Ps 121:3

“Jerusalem, which is built as a city, which is compact together.”

“Together. Well built and inhabited. The Jews throughout the world considered it as their most dear country. (Calmet) — The participation of spiritual graces (Psalm cxviii. 63., &c.) is a great comfort to Catholics, (Worthington) who look upon the chair of St. Peter at Rome as the centre of unity. (Haydock) — David established order in Jerusalem, when he had made the conquest, and various families contributed to the rebuilding of it. (Berthier) — All the tribes were united under the dominion of David. (Houbigant)”
