1 Kings 6:31-33

31For the entrance of the inner sanctuary he made doors of olive wood; the lintel and doorposts were one-fifth of the wall.

32The two doors were of olive wood; and he carved on them figures of cherubim, palm trees, and open flowers, and overlaid them with gold; and he spread gold on the cherubim and on the palm trees.

33So for the door of the sanctuary he also made doorposts of olive wood, one-fourth of the wall.
