2 Chronicles 3:9-13

And the weight of the nails was fifty shekels of gold. And he overlaid the upper chambers with gold.

And in the most holy house he made two cherubims of image work, and overlaid them with gold.

And the wings of the cherubims were twenty cubits long: one wing of the one cherub was five cubits, reaching to the wall of the house: and the other wing was likewise five cubits, reaching to the wing of the other cherub.

And one wing of the other cherub was five cubits, reaching to the wall of the house: and the other wing was five cubits also, joining to the wing of the other cherub.

The wings of these cherubims spread themselves forth twenty cubits: and they stood on their feet, and their faces were inward.
