1 Kings 6:18 ASV

¹⁶  And he built twenty cubits on the hinder part of the house with boards of cedar from the floor unto the walls 'of the ceiling': he built 'them' for it within, for an oracle, even for the most holy place.

¹⁷  And the house, that is, the temple before 'the oracle', was forty cubits 'long'.

¹⁸  And there was cedar on the house within, carved with knops and open flowers: all was cedar; there was no stone seen.

¹⁹  And he prepared an oracle in the midst of the house within, to set there the ark of the covenant of Jehovah.

²⁰  And within the oracle was 'a space of' twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof; and he overlaid it with pure gold: and he covered the altar with cedar.
