And for the entering of the oracle he made doors of olive tree: the lintel and side posts were a fifth part of the wall.
Context
30 He overlaid the floor of the house with gold, inside and outside.
31 For the entrance of the inner sanctuary, he made doors of olive wood. The lintel and door posts were a fifth part of the wall.
32 So he made two doors of olive wood; and he carved on them carvings of cherubim, palm trees, and open flowers, and overlaid them with gold. He spread the gold on the cherubim and on the palm trees.
