Only on Account of Israel
“The blessed Holy One scattered Israel among the peoples only so that they may accumulate converts, for it is said: And I will sow her for Myself in the earth; [and I will have mercy upon her that had not obtained mercy; and I will say to them who were not My people, you are My people; and they shall say, You are my God] (Hosea 2:25)—surely, a man sows a se’ah in order to harvest many korin” (BT Pesaḥim 87b, cf. Zohar 1:244a).
“Come and see: All nations of the world and all kings of the world are empowered only on account of Israel. Egypt did not rule over the whole world until Israel came, entering exile; then they overwhelmed all nations of the world. Babylon overpowered all nations of the world only so that Israel would be exiled among them. Edom overpowered all nations of the world only on account of Israel—so that they would be exiled among them. For these nations had been subdued by other nations and were lower than all of them, but on account of Israel they became powerful…. Why? Because Israel alone corresponds to all nations of the world” (Zohar 2:6a).
