'Likeness' in the Bible

As the appearance of the rainbow in the clouds on a rainy day, so was the appearance of the surrounding radiance. Such was the appearance of the likeness of the glory of the Lord. And when I saw it, I fell on my face and heard a voice speaking.

Then I looked, and behold, a likeness as the appearance of a man; from His loins and downward there was the appearance of fire, and from His loins and upward the appearance of brightness, like the appearance of glowing metal.

As for their appearance, all four of them had the same likeness, as if one wheel were within another wheel.

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 ahead.
