1 Kings 6:31-33

31And for the entrance of the oracle he made doors of olive-wood: the lintel [and] side posts were the fifth part [of the breadth of the house].

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

33And he also made for the doorway of the temple posts of olive-wood, of the fourth part [of the breadth of the house].
