Although Amalek had not received the merited punishment from the hands of Joshua, still his enterprise against Israel had not been entirely unavailing. The miraculous exodus of Israel out of Egypt, and especially the cleaving of the sea, had created such alarm among the heathens, that none among them had dared to approach Israel. But this fear vanished as soon as Amalek attempted to compete in battle with Israel. Although he was terrible beaten, still the fear of the inaccessibility of Israel was gone. It was with Amalek as with that foolhardy wight who plunged into a scalding-hot tub. He scalded himself terribly, yet the tub became cold through his plunge into it. Hence God was not content with the punishment Amalek received in the time of Moses, but swore by His throne and by His right hand that He would never forget Amalek's misdeeds, that in this world as well as in the time of the Messiah He would visit punishment upon him, and would completely exterminate him in the future world. So long as the seed of Amalek exist, the face of God is, as it were, covered, and will only then come to view, when the seed of Amalek shall have been entirely exterminated. God had at first left the war against Amalek in the hands of His people, therefore He bade Joshua, the future leader of the people, never to forget the war against Amalek; and if Moses had listened intently, he would have perceived from this command of God that Joshua was destined to lead the people into the promised land. But later, when Amalek took part in the destruction of Jerusalem, God Himself took up the war against Amalek, saying, "By My throne I vow not to leave a single descendant of Amalek under the heavens, yea, no one shall even be able to say that this sheep or that wether belonged to an Amalekite." [147] God bade Moses impress upon the Jews to repulse no heathen should he desire conversion, but never to accept an Amalekite as a proselyte. It was in consideration of this word of God that David slew the Amalekite, who announced to him the death of Saul and Jonathan; for he saw in him only a heathen, although he appeared in the guise of a Jew.
