For he said, because the Lord hath sworn,.... So some Jewish writers take it for an oath, as we do; or "because the hand is on the throne of the Lord" ; which the Targum of Jonathan, Jarchi, and Aben Ezra, interpret of the hand of the Lord being lifted up, of his swearing by the throne of his glory; but, as Drusius observes, it is not credible that God should swear by that which is prohibited by Christ, Mt 5:24 rather the words are to be rendered, "because the hand", that is, the hand of Amalek, "is against the throne of the Lord" ; against his people, among whom his throne was, and over whom he ruled, so against himself, and the glory of his majesty; because he was the first that made war upon Israel, when the Lord brought them out of Egypt, and unprovoked fell upon their rear, and smote the hindmost, faint and weary among them: thereforethe Lord will have war with Amalek from generation to generation; until they are utterly destroyed; and so in fact he had, and thus it was.
The Targum of Jonathan is,"he by his word will make war against those that are of the house of Amalek, and destroy them to three generations, from the generation of this world, from the generation of the Messiah, and from the generation of the world to come;''and Baal Hatturim on the place observes, that this phrase, "from generation to generation", by gematry, signifies the days of the Messiah.
Amalek may be considered as a type of antichrist, whose hand is against the throne of God, his tabernacle, and his saints; who, with all the antichristian states which make war with the Lamb, will be overcome and destroyed by him.
