Ezekiel 1:28, 9, 14
 As the appearance of the bow that is in the cloud in the day of rain, so was the appearance of the brightness round about. This was the appearance of the likeness of the glory of the LORD. And when I saw it, I fell upon my face, and I heard a voice of one that spake.
 Their wings were joined one to another; they turned not when they went; they went every one straight forward.
 And the living creatures ran and returned as the appearance of a flash of lightning.
