Kabbalah zu Jechezkiel 1:1

"And the living creatures ran and returned" (Yechezkel 1:1 4); the eye is not able to observe the revealed living creatures as they run to and fro. This is because the wheel that is stationed in their midst is Metatron, who is far greater and more important than the rest of (the living creatures), higher than they by 500 parasangs.

"He slew two lion-hearted men of Moab" (II Samuel 23:20). Two Temples existed and were sustained on his account: The first Temple and the second. However, as he was gone, the flow from above stopped. It is as if he "slew," destroyed, and ended them. And the holy throne collapsed. As it is written, "As I was in exile" (Ezekiel 1:1). (Meaning) that a certain grade, which is called I (Heb. אֲנִי, Aleph-Nun-Yud) was in exile. Where? "By the river Kevar" (Ibid.) By the river that had sprouted and flowed from Kevar (already), or in other words, by the river that had already sprouted and flowed, all its waters and fountains have dried up, (and) does not flow as before.
