1 Kings 6:31-33

31 For the entrance to the inner sanctuary he made doors out of olive wood that were one fifth of the width of the sanctuary.
32 And on the two olive-wood doors he carved cherubim, palm trees and open flowers, and overlaid the cherubim and palm trees with hammered gold.
33 In the same way, for the entrance to the main hall he made doorframes out of olive wood that were one fourth of the width of the hall.
