1 Kings 6:9

So he built the house i.e. The Temple building. The next verse speaks of the enclosing framework of chambers. What was now finished was the portion for divine service.

and covered the house i.e. Made the roof for it. On this roof, see Fergusson, Temples of the Jews, pp. 19 seqq., where the author shews that the covering of the Tabernacle was made with a ridge and sloped to both sides, and that the cedar beams and boards (R.V. planks) spoken of in this verse were to imitate, as nearly as could be done in wood, the Tabernacle roof. Mr Fergusson has suggested (p. 28) that there were most probably pillars inside the Temple to support the beams of the roof. -No cedar beams that were available could be laid across an opening 30 feet free without sagging to an unpleasant extent."
