'Platform' in the Bible

Over the heads of the living beings was something like a platform, glittering awesomely like ice, stretched out over their heads.

Under the platform their wings were stretched out, each toward the other. Each of the beings also had two wings covering its body.

Then there was a voice from above the platform over their heads when they stood still.

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 saw on the platform above the top of the cherubim something like a sapphire, resembling the shape of a throne, appearing above them.

I saw that the temple had a raised platform all around; the foundations of the side chambers were a full measuring stick of 10? feet high.
