Why the Throne and the Name Stay Incomplete Until Amalek Falls

"And he said: For a hand is upon the throne of the LORD; the LORD will have war with Amalek" (Exodus 17:16). It was taught in the name of Rabbi Eliezer: The Holy One, blessed be He, swore an oath: "By My right hand, by My right hand; by My throne, by My throne": that if converts come from all the nations of the world, I will accept them, but from the seed of Amalek I will never accept them. David too acted thus, as it says, "And David said to the young man who told him: From where are you? And he said: I am the son of a stranger, an Amalekite" (2 Samuel 1:13). Rabbi Isaac said: He was Doeg the Edomite. "And David said to him: Your blood be upon your head" (2 Samuel 1:16). Rabbi Isaac said: It is written "your bloods" [in the plural]; he said to him: Much blood you spilled at Nob, the city of priests. "From generation" (Exodus 17:16). The Holy One, blessed be He, said: What is "generation, generation"? I will pursue after him for generations of generations. Rabbi Eliezer and Rabbi Joshua and Rabbi Yose: Rabbi Eliezer said, from the generation of Moses until the generation of Samuel. Rabbi Joshua said, from the generation of Samuel until the generation of Mordecai and Esther. Rabbi Yose said, from the generation of Mordecai and Esther until the generation of the King Messiah, which is three generations. And from where do we know that the generation of the King Messiah is three generations? As it is written, "They shall fear You with the sun, and before the moon, generation of generations" (Psalms 72:5): "generation," one; "generations," two; behold, three. Rabbi Berekhiah in the name of Rabbi Abba bar Kahana: As long as the seed of Amalek exists in the world, it is, as it were, as though a wing covers the face; once the seed of Amalek is destroyed from the world, "your Teacher will no longer hide Himself, and your eyes shall see your Teacher" (Isaiah 30:20). Rabbi Levi in the name of Rabbi Huna son of Rabbi Hanina: As long as the seed of Amalek exists in the world, neither is the Name whole nor is the throne whole; once the seed of Amalek is destroyed from the world, the Name is whole and the throne is whole. And what is the reason? "The enemy is finished, ruins forever, and cities You have uprooted; their very memory is perished" (Psalms 9:7), and what is written after it? "But the LORD sits enthroned forever; He has established His throne for judgment" (Psalms 9:8). The portion is concluded.
