Ezekiel 10:1-2
1
Then I looked, and see, in the expanse 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.
2
He spoke to the man clothed in linen, and said, Go in between the whirling [wheels], even under the cherub, and fill both your hands with coals of fire from between the cherubim, and scatter them over the city. He went in as I watched.
