'Expanse' in the Bible

Have you considered closely [the] earth's vast expanse? Declare [it], if you know all of it.

Now [the] likeness above the heads of the living creatures [was] an expanse like the outward appearance of {awesome} {ice} spread out above their heads {upward}.

And under the expanse their wings [were stretched out] straight {one toward the other}; each had two [wings] covering them, and each had two [wings] covering their bodies.

And there was a sound from above the expanse that [was] above their heads, {and when they stood} they lowered their wings.

And from above the expanse that [was] above their heads [there was] the likeness of a throne, {looking like a sapphire}, and above the likeness of the throne [was] a likeness similar to [the] appearance of a human on it, [but] {above it}.

And I looked, and look! On the expanse that [was] above the head of the cherubim [something] like a stone of sapphire, [and] like [the] appearance of [the] shape of a throne it appeared above them.

But the [ones] having insight will shine like the brightness of the expanse, and [the ones] providing justice [for] the many [will be] like the stars {forever and ever}.
