Kabbalah Zakharia 14:9: Zohar, Pardes Rimmonim, The Beginning & Sha'arei Orah

The Holy One, blessed be He, outside His place is not a King. When He returns to His place, "Hashem shall be King" (Zechariah 14:9). It is said of Israel as well that all Israel are princes [Literally, 'the sons of kings']. Like the father, so are the sons. The children are not princes until they return to the land of Israel. You may say that he is a commoner, though he is a commoner in relation to his Master, do not treat lightly a blessing from a commoner, for this commoner is the servant Metatron. The first man, who did not keep the glory he was given [ because he ate from the Tree when he was not supposed to do so], was brought down to eat together with his donkey, and he said {to Hashem} 'I and my donkey shall eat from the same trough'. Issachar merited this donkey by being called, "Issachar is a strong donkey" (Genesis 49:14).

After we were in the previous chapter forced [to accept] that there is no room to enquire for the necessity of our traditions, as we possess perfect compulsion, as we have explained. We will say that similarly it is not [on us] to enquire for the reason for the Emanator, why He emanated ten [Sefirot] and not twenty and not five and similar (also the question shall not occur because the objection is not connected to the case). And it is proper that we examine this whole emanation: why was it emanated? And with our answers to this, everything will be settled.

And with this we have found, on the contrary, that all the time the world [is] in the corruption from the filth of the serpent and the husk, the emanated entities are not connecting themselves as is proper, and His Divinity is not revealed and the knowledge in the people of Israel has completely come to an end, until He shows mercy from the heavens and the world will rise from the filth of the serpent and will be arranged as is proper; and then the world will return to its [proper] arrangement, and His divinity will reveal itself in the lower ones [= degrees] as is suitable and proper, and the sons of man will increase strength⁵An allusion to Job 17:9 with their knowledge of Him. And then it is said (Jeremiah 31:33): “And man will not teach his neighbor etc., …. because they all, from small to great, will know Me”. And then the light of the Torah will reveal itself and its hidden things and its mysteries as is fitting and as is proper, and the emanated entities will connect themselves [in] perfect union, as Scripture establishes, as it is written (Zechariah 14:9): “And HaShem will be king for all the earth, on that day HaShem will be one and His name one”.
