1 Kings 6:16

And he built twenty cubits on the sides of the house ,.... At the end or extremity of it, as the Targum; that is, he built the most holy place, which was twenty two cubits long, at the end of the holy place, which he wainscotted as the other:

both the floor and the walls with boards of cedar ; or from the floor, including that, to the walls on each side, from wall to wall, and taking in them, they were all lined with cedar wood:

he even built them for it within, even for the oracle, even for the most holy place ; which explains what building is spoken of, and that the inside of that was covered with cedar from bottom to top.
