'Innermost' in the Bible

and the snuffers, and the bowls, and the spoons, and the censers, of gold refined, and the opening of the house, its innermost doors to the holy of holies, and the doors of the house to the temple, of gold.

And Micaiah saith, 'Lo, thou dost see in that day, that thou dost enter into the innermost chamber to be hidden.'
