'Appeared' in the Bible

Above the platform over their heads was something like a sapphire shaped like a throne. High above on the throne was a form that appeared to be a man.

As I watched, I noticed a form that appeared to be a man. From his waist downward was something like fire, and from his waist upward something like a brightness, like an amber glow.

(The cherubim appeared to have the form of human hands under their wings.)

As I watched, I saw tendons on them, then muscles appeared, and skin covered over them from above, but there was no breath in them.
