'Part' in the Bible

And he built twenty cubits of the innermost part of the house, both floor and walls, with boards of cedar; and he built them for it within, to be the oracle, the most holy place.

And 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.

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