Ezekiel 1:25 - 1:28
25 And there came a sound from above the expanse that was over their heads; whenever they stood still, they dropped their wings. 26 Now above the expanse that was over their heads there was something in the likeness of a throne, like sapphire stone in appearance; and upon the likeness of the throne, high up, was the likeness of one with the appearance of a man. 27 Then I saw from the appearance of His loins and upward something like the gleam of glowing metal with the appearance of fire all around within it, and from the appearance of His loins and downward I saw something with the appearance of fire; and there was a radiance all around Him. 28 As the appearance of the rainbow in the clouds on a rainy day, so was the appearance of the radiance all around. Such was the appearance of the likeness of the glory of Yahweh. And I saw this, and I fell on my face and heard a sound of a voice speaking.
