'Algum trees' in the Bible

And send me cedar trees, fir trees, and algum trees out of Lebanon. For I know that your servants are skillful to cut timber in Lebanon. And, behold, my servants shall be with your servants

And also the servants of Hiram, and the servants of Solomon who brought gold from Ophir, brought algum trees and precious stones.

And the king made terraces to the house of Jehovah with the algum trees, and terraces to the king's palace, and lyres and harps for singers. And there were none such seen before in the land of Judah.
