2 Chronicles 3:6-8

6He adorned the house with settings of precious stones. The gold was gold of Parvaim.

7So he lined the house with gold—its beams, its thresholds, its walls, and its doors—and he carved cherubim on the walls.

8And he made the Most Holy Place. Its length, corresponding to the breadth of the house, was twenty cubits, and its breadth was twenty cubits. He overlaid it with 600 talents of fine gold.
