'Space' in the Bible

Yet there shall be a space between you and it, about two thousand cubits by measure: come not near unto it, that ye may know the way by which ye must go: for ye have not passed this way heretofore.

And the sun was at rest and the moon kept its place till the nation had given punishment to their attackers. (Is it not recorded in the book of Jashar?) So the sun kept its place in the middle of the heavens, and was waiting, and did not go down, for the space of a day.
