1 Kings 6:16-18

16And he built twenty cubits on the sides of the house, both the floor and the walls with boards of cedar: he even built them for it within, even for the oracle, even for the most holy place.

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

18And the cedar of the house within was carved with knops and open flowers: all was cedar; there was no stone seen.12
