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

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

Within the oracle was twenty cubits in length, and twenty cubits in breadth, and twenty cubits in its height; and he overlaid it with pure gold: and he covered the altar with cedar.
