(1.) What God will do for Zion we are told, v. 17. [1.] Her friends, who had deserted her, shall be gathered to her, and shall contribute their utmost to her assistance and comfort: Thy children shall make haste. Converts to the faith of Christ are the children of the church; they shall join themselves to her with great readiness and cheerfulness, and flock into the communion of saints, as doves to their windows. "Thy builders shall make haste" (so some read it), "who shall build up thy houses, thy walls, especially thy temple; they shall do it with expedition." Church work is usually slow work; but, when God's time shall come, it shall be done suddenly. [2.] Her enemies, who had threatened and assaulted her, shall be forced to withdraw from her: Thy destroyers, and those who made thee waste, who had made themselves masters of the country and ravaged it, shall go forth of thee. By Christ the prince of this world, the great destroyer, is cast out, is dispossessed, has his power broken and his attempts quite baffled.
