"Then I looked, and behold, in the firmament that was over the head of the cherubim there appeared above them as it were a sapphire stone, as the appearance of the likeness of a throne." — Ezekiel 10:1 (ASV)

As it were a sapphire stone. —Compare Ezekiel 1:26. No mention is here made of a being upon the throne, but it is implied by the he spoke of the following verse. The word cherubim corresponds throughout this chapter to the living creatures of Ezekiel 1:0.
