1 Kings 6:15-19

He built the walls of the house on the inside with boards of cedar; from the floor of the house to the ceiling he paneled the walls on the inside with wood, and he paneled the floor of the house with boards of juniper.

He also built twenty cubits on the rear part of the house with boards of cedar from the floor to the ceiling; he built them for it on the inside as an inner sanctuary, as the Most Holy Place.

The house, that is, the main room in front of the inner sanctuary, was forty cubits long.

There was cedar inside the house, carved in the shape of gourds and open flowers; everything was cedar, there was no stone visible.

Then he prepared an inner sanctuary inside the house in order to place there the ark of the covenant of the Lord.
