'Likeness' in the Bible

Within it there were figures resembling four living beings. And this was their appearance: they had human form.

Regarding the form and appearance of their faces: they [each] had the face of a man [in front], and each had the face of a lion on the right side, and the face of an ox on the left side; all four also had the face of an eagle [at the back of their heads].

Now stretched over the heads of the living beings there was something like an expanse, looking like the terrible and awesome shimmer of icy crystal.

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.

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.

Then I looked, and behold, a likeness [of a man] with the appearance of fire; from His loins downward He was like fire, and from His loins upward He had the appearance of brightness, like gleaming metal (bronze).

As for the likeness of their faces, they were the same faces whose appearance I had seen by the River Chebar. Each one went straight forward.
