Ezekiel 10:1-2

And I looked, and there in the firmament that was above the head of the cherubim, there appeared something like a sapphire stone, having the appearance of the likeness of a throne. Then He spoke to the man clothed with linen, and said, “Go in among the wheels, under the cherub, fill your hands with coals of fire from among the cherubim, and scatter them over the city.” And he went in as I watched.
