2. When this is done the glory of the Lord shall be revealed, v. 5. (1.) When the captives are prepared for deliverance Cyrus shall proclaim it, and those shall have the benefit of it, and those only, whose hearts the Lord shall stir up with courage and resolution to break through the discouragements that lay in their way, and to make nothing of the hills, and valleys, and all the rough places. (2.) When John Baptist has for some time preached repentance, mortification, and reformation, and so made ready a people prepared for the Lord (Luke i. 17), then the Messiah himself shall be revealed in his glory, working miracles, which John did not, and by his grace, which is his glory, binding up and healing with consolations those whom John had wounded with convictions. And this revelation of divine glory shall be a light to lighten the Gentiles. All flesh shall see it together, and not the Jews only; they shall see and admire it, see it and bid it welcome; as the return out of captivity was taken notice of by the neighbouring nations, Ps. cxxvi. 2. And it shall be the accomplishment of the word of God, not one iota or tittle of which shall fall to the ground: The mouth of the Lord has spoken it, and therefore the hand of the Lord will effect it.
