זוהר שמות — דף קכ ע”ב

Israel, like a doe, is pursued by the lions of the wicked nations. Naphtali — the swift doe — will awaken on the right: the eagle-lion, the Messiah son of David. The eagle protects from the nations and devours their mixture. After the purification, Israel will gather in Jerusalem. Israel is like grain separated from straw and chaff; until they are purified, the yod does not rest upon the heh. After the purification, He will call them: my firstborn son Israel.
