Midrash su Salmi 83:6

Rabbi José said: When Sennacherib came to the land (of Israel), all the nations who were in the regions round about the land of Israel saw the camp of Sennacherib, and feared greatly, and every man fled from his place, as it is said, "I have removed the bounds of the peoples, and have robbed their treasures" (Isa. 10:13). They went into the wilderness, and intermixed with the children of Ishmael, and all of them were (composed of) ten peoples, as it is said, "The tents of Edom, and the Ishmaelites; Moab, and the Hagarenes; Gebal, and Ammon, and Amalek; Philistia, with the inhabitants of Tyre; Assyria also is joined with them" (Ps. 83:6, 7, 8). All of them are destined to fall by the hand of the Son of David, as it is said, "O my God, make them like the whirling dust" (Ps. 83:13). "As the fire that burneth the forest, and as the flame that setteth the mountains on fire" (Ps. 83:14). "So pursue them with thy tempest, and terrify them with thy storm" (Ps. 83:15).
