Bible Verses About The First Temple: Was twenty cubits every way

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.

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.
