'Innermost' in the Bible

And he built twenty cubits of the innermost part of the house, both floor and walls, with boards of cedar; and he built them for it within, to be the oracle, the most holy place.

the cups, snuffers, bowls, spoons, firepans—of pure gold; and the hinges of gold [both] for the doors of the inner house, the Holy of Holies, and for the doors of the house, the main room [the Holy Place].

And those left flee to Aphek, unto the city, and the wall falleth on twenty and seven chief men who are left, and Ben-Hadad hath fled, and cometh in unto the city, into the innermost part.

And Micaiah saith, 'Lo, thou art seeing on that day, when thou goest in to the innermost chamber to be hidden.'
