1 Kings 6:20-22

20This inner sanctuary was 30 feet long, 30 feet wide, and 30 feet high. He overlaid the inside with solid gold. He also overlaid the altar made of cedar.

21Then Solomon overlaid the rest of the Temple’s interior with solid gold, and he made gold chains to protect the entrance to the Most Holy Place.

22So he finished overlaying the entire Temple with gold, including the altar that belonged to the Most Holy Place.
