Isaías 11:13 Cabalá: Sha'arei Kedusha & Heikhalot Rabbati

Moshiach, the son of David, will not come until the spirit of envy is removed, as written,⁴⁵³Isaiah 11:13 “The jealousy of Ephraim shall cease and the oppressors of Yehudah shall be cut off; Ephraim shall not be jealous of Yehudah and Yehudah will not harass Ephraim.” Moreover, even the Supernal angels fell from their holiness as the result of envy, as written in Pirkei d’Rabbi Eliezer,⁴⁵⁴Pirkei d’Rabbi Eliezer, Ch. 13-14 that the angel Sama’el was greater than all the Seraphim angels, in that they only had six wings, whereas he had twelve wings. He nonetheless was uprooted from the side of holiness because he was envious of man. The same is said of the Nefillim angels, Aza and Aza’el, who were excised from the world because they were jealous of man.⁴⁵⁵Pesikta Rabbati 34:1; Yoma 67b and Rashi there; Zohar I 37a.

And the elders looked, for he was despised and dressed in rags, they scorned him as she had scorned the elders, for he was despised, and his anger burned within him. And he removed his garments from upon him and wore garments of vengeance, a costume. And the prophet Elijah came with him, and they went to Jerusalem. And he revived Nehemiah son of Hushiel, who was buried in the gates of Jerusalem. And they went to the congregation of Israel, and the children of Israel saw him, that Nehemiah was with him, and they believed in Menahem son of Amiel, the word of Metatron and Mikael, the prince of the host of the Lord. In truth, Ephraim will not be jealous of Judah (Isaiah 11:13), and a counsel of peace will be between them (Zechariah 6:13). And on the twenty-seventh of the first month, the ruins of Jerusalem for eight hundred and ninety years, salvation to the Lord.
