The Enarrations, or Expositions, on the Psalms

⁴ Let the Psalm then follow, and say, “God shall be known in her houses.” Now in her “houses,” because of the mountains, because of the two walls, because of the two sons. “God shall be known in her houses,” but he commends grace, therefore he added, “when He shall take her up.” For what would that city have been, unless He had taken her up? Would it not immediately have fallen, unless it had such foundation? For “other foundation can no man lay than that is laid, which is Jesus Christ.” Let none then glory in his own merits; but “he that glories, let him glory in the Lord.”...The Lord then has taken up this city, and is known therein, that is, His grace is known in that city: for whatever that city has, which glories in the Lord, it has not of itself. For because of this it is said, “What have you that thou did not receive?”
