Ezekiel 10:1-2

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. And he spake unto the man clothed in linen, and said, Go in between the whirling wheels, even under the cherub, and fill both thy hands with coals of fire from between the cherubim, and scatter them over the city. And he went in in my sight.
