1 Kings 6:17

15 And he built the walls of the house within with boards of cedar, both the floor of the house, and the walls of the cieling: and he covered them on the inside with wood, and covered the floor of the house with planks of fir.

16 And he built twenty cubits on the sides of the house, both the floor and the walls with boards of cedar: he even built them for it within, even for the oracle, even for the most holy place.

And the house, that is, the temple before it, was forty cubits long.

18 And the cedar of the house within was carved with knops and open flowers: all was cedar; there was no stone seen.

19 And the oracle he prepared in the house within, to set there the ark of the covenant of the LORD.

Here the Bible tells a story about someone else. Ask yourself what it can say to us today. Do read the surrounding verses too, because the context often says more than a single verse.
