1 Kings 6:16

16 And he builded a wall of boards of cedar of twenty cubits at the hinder part of the temple, from the pavement unto the higher parts; and he made the inner house of God's answering place into the holy of holy things, (and he made the Inner Temple, that is, the Most Holy Place, or the Holy of Holies).

1 Kings 6:16 Meaning and Commentary

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.

1 Kings 6:16 In-Context

14 Therefore Solomon builded the house, and ended it; (And so Solomon built the House, and finished it;)

15 and he builded the walls of the house within with boards of cedar, from the pavement of the house unto the highness of the wall, and unto the couples; and he covered them with wood of cedar within; and he covered the pavement of the house with boards of box. (and he built the walls of the House within out of cedar boards, from the floor of the House unto the top of the wall, and unto the couplings; and he covered them with cedar wood within; and he covered the floor of the House with fir, or pine, boards.)

16 And he builded a wall of boards of cedar of twenty cubits at the hinder part of the temple, from the pavement unto the higher parts; and he made the inner house of God's answering place into the holy of holy things, (and he made the Inner Temple, that is, the Most Holy Place, or the Holy of Holies).

17 And that temple before the doors of God's answering place was of forty cubits. (And the chamber in front of the doors of the Inner Temple was forty cubits in length.)

18 And all the house within was clothed with cedar, and had his smoothnesses, and his joinings made subtly, and gravings appearing above; all things were clothed with boards of cedar, and utterly a stone might not appear in the wall. (And all the House within was covered with cedar, and had carvings of knops, or of gourds, and open flowers; everything was covered with cedar boards, and no stone appeared, or was visible, utterly anywhere on the wall.)
