2 Chronicles 3:8-9
8-9He made the Holy of Holies a cube, thirty feet wide, long, and high. It was veneered with six hundred talents (something over twenty-two tons) of gold. The gold nails weighed fifty shekels (a little over a pound). The upper rooms were also veneered in gold.
10-13He made two sculptures of cherubim, gigantic angel-like figures, for the Holy of Holies, both veneered with gold. The combined wingspread of the side-by-side cherubim (each wing measuring seven and a half feet) stretched from wall to wall, thirty feet. They stood erect facing the main hall.
