1 Kings 6:18-20

Young's Literal Translation

¹⁸ And the cedar for the house within [is] carvings of knobs and openings of flowers; the whole [is] cedar, there is not a stone seen.

¹⁹ And the oracle in the midst of the house within he hath prepared, to put there the ark of the covenant of Jehovah.

²⁰ And before the oracle [is] twenty cubits in length, and twenty cubits in breadth, and twenty cubits [is] its height; and he overlayeth it with gold refined, and overlayeth the altar with cedar.
