2 Chronicles 3:8-14

He made the Most Holy Place 30 feet wide, corresponding to the width of the Temple, and 30 feet deep. He overlaid its interior with 23 tons of fine gold. The gold nails that were used weighed 20 ounces each. He also overlaid the walls of the upper rooms with gold. He made two figures shaped like cherubim, overlaid them with gold, and placed them in the Most Holy Place. The total wingspan of the two cherubim standing side by side was 30 feet. One wing of the first figure was 7-1/2 feet long, and it touched the Temple wall. The other wing, also 7-1/2 feet long, touched one of the wings of the second figure. In the same way, the second figure had one wing 7-1/2 feet long that touched the opposite wall. The other wing, also 7-1/2 feet long, touched the wing of the first figure. So the wingspan of the two cherubim side by side was 30 feet. They stood on their feet and faced out toward the main room of the Temple. Across the entrance of the Most Holy Place he hung a curtain made of fine linen, decorated with blue, purple, and scarlet thread and embroidered with figures of cherubim.
