John Gill Bible Commentary

Their Redeemer is strong, the Lord of hosts is his name,.... And seeing his name is the Lord of hosts or armies, and has all the armies of heaven and earth at his command; and especially since he is Jehovah, the everlasting and unchangeable I AM; he must be strong and mighty, yea, the Almighty, and so able to redeem his Israel, as the Messiah was, who is here intended; from sin, Satan, and the world; from the law, its curse and condemnation; from death and hell, and wrath to come; as well as to deliver his people from the Romish yoke, and to avenge them on all their enemies: he shall thoroughly plead their cause; with God and man; he that is the Redeemer of men is their advocate with the Father; with whom he pleads on their behalf his blood, righteousness and sacrifice, for all blessings of grace and glory; and to all charges of law and justice, and their own hearts, and the condemnings of them; and he pleads their cause with men, and rights their wrongs, and avenges the injuries done them by antichrist and others, Rev 19:2; that he may give rest to the land; not to the land of Judea only, but to the whole world; which will be at rest and in peace upon the destruction of mystical Babylon, and the conversion of the Jews, and their return to their own land; as well as the Messiah will give spiritual rest to all the redeemed ones here, and eternal rest, which remains for the people of God, hereafter: and disquiet the inhabitants of Babylon; by the destruction of it and them; and rendering tribulation to them that trouble his people; and by punishing antichrist with the vials of his wrath, and with everlasting damnation, the smoke of whose torment shall ascend for ever and ever, Th2 1:6.
