'Heaven' in the Bible

For the Christ is not entered into holy places made with hand, figures of the true, but into heaven itself, now to appear before the face of God for us:

Wherefore also there have been born of one, and that of one become dead, even as the stars of heaven in multitude, and as the countless sand which is by the sea shore.

the universal gathering; and to the assembly of the firstborn who are registered in heaven; and to God, judge of all; and to the spirits of just men made perfect;

See that ye refuse not him that speaks. For if those did not escape who had refused him who uttered the oracles on earth, much more we who turn away from him who does so from heaven:

whose voice then shook the earth; but now he has promised, saying, Yet once will I shake not only the earth, but also the heaven.
