1 Kings 6:19-21

Young's Literal Translation

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.

²¹ And Solomon overlayeth the house within with gold refined, and causeth [it] to pass over in chains of gold before the oracle, and overlayeth it with gold.
