'Olive tree' in the Bible

And within the oracle he made two cherubims of olive tree, each ten cubits high.

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.

The two doors also were of olive tree; and he carved upon them carvings of cherubims and palm trees and open flowers, and overlaid them with gold, and spread gold upon the cherubims, and upon the palm trees.

So also made he for the door of the temple posts of olive tree, a fourth part of the wall.
