'Heaven' in the Bible

For Christ entered not into a holy place made with hands, like in pattern to the true; but into heaven itself, now to appear before the face of God for us:

wherefore also there sprang of one, and him as good as dead,'so many as the stars of heaven in multitude, and as the sand, which is by the sea-shore, innumerable.

to the general assembly and church of the firstborn who are enrolled in heaven, and to God the Judge of all, and to the spirits of just men made perfect,

See that ye refuse not him that speaketh. For if they escaped not when they refused him that warned them on earth, much more'shall not we escape who turn away from him that warneth from heaven:

whose voice then shook the earth: but now he hath promised, saying, Yet once more will I make to tremble not the earth only, but also the heaven.
