1 Kings 6:19-21

ERV(i) 19 And he prepared an oracle in the midst of the house within, to set there the ark of the covenant of the LORD. 20 And within the oracle was [a space of] twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof; and he overlaid it with pure gold: and he covered the altar with cedar. 21 So Solomon overlaid the house within with pure gold: and he drew chains of gold across before the oracle; and he overlaid it with gold.
