'Almug trees' in the Bible

And the navy also of Hiram, that brought gold from Ophir, brought in from Ophir great plenty of almug-trees and precious stones.

And the king made of the almug-trees pillars for the house of Jehovah, and for the king's house, harps also and psalteries for the singers: there came no such almug-trees, nor were seen, unto this day.
