Another matter, the enemy's swords have been destroyed. Teach in the name of Rabbi Elazar, the Holy One, blessed be He, swore an oath on His throne of glory not to leave a memory of Amalek under the heavens. (Job 18:19) "He has no offspring or descendant among his people." So that it may not be said that this tree belonged to Amalek, as it is said, "Their memory has perished." Rabbi Levi said in the name of Rabbi Ḥama: As long as the seed of Amalek exists, the Name is not whole and the throne is not whole, as it is stated: "Because there is a hand on the throne of the Lord." (Exodus 17:16) It should have said, "on the throne of God."
And when the memory of Amalek is obliterated from the world, the Name will be whole and the throne will be whole. As it is written, "The enemy's swords have been destroyed forever." (Psalms 9:7) What is written afterwards? "And the Lord shall endure forever; He has established His throne for judgment." (Psalms 9:8)
