As a priest, Ezekiel is fundamentally concerned with the "Kavod YHWH", a technical phrase meaning the presence (shekhinah) of YHWH (i.e., one of the Names of God) among the people, in the Tabernacle, and in the Temple, and normally translated as "glory of God". In Ezekiel the phrase describes God mounted on His throne-chariot as he departs from the Temple in chapters 1–11 and returns to what Marvin Sweeney describes as a portrayal of "the establishment of the new temple in Zion as YHWH returns to the temple, which then serves as the center for a new creation with the tribes of Israel arrayed around it" in chapters 40–48. The vision in chapters 1:4–28 reflects common mythological/Biblical themes and the imagery of the Temple: God appears in a cloud from the north – the north being the usual home of God/the gods in ancient mythology and Biblical literature – with four living creatures corresponding to the two cherubim above the Mercy Seat of the Ark of the Covenant and the two in the Holy of Holies, the innermost chamber of the Temple; the burning coals of fire between the creatures perhaps represents the fire on the sacrificial altar, and the famous "wheel within a wheel" may represent the rings by which the Levites carried the Ark, or the wheels of the cart.
