Ezekiel 1:24-28

As they moved, I also heard the sound of their wings like the sound of great [rushing] waters, like the voice of the Almighty, the sound of tumult like the noise of an army camp. Whenever they came to a stop, they lowered their wings. And there was a voice above the expanse that was over their heads; whenever they stopped, they lowered their wings. Now above the expanse that was over their heads there was something resembling a throne, it appeared like [it was made of] sapphire or lapis lazuli; and [seated] on that which looked like a throne, high up, was a figure with the appearance of a man. [Phil 2:5-8] Now upward, from that which appeared to be His waist, I saw something like glowing metal that looked like it was filled with fire all around it; and downward, from that which appeared to be His waist, I saw something like fire; and there was a brightness and a remarkable radiance [like a halo] around Him. As the appearance of the rainbow in the clouds on a rainy day, so was the appearance of the surrounding radiance. This was the appearance of the likeness of the glory and brilliance of the LORD. And when I saw it, I fell face downward and I heard a voice of One speaking. [Rev 4:3]
