'Fir' in the Bible

And Hiram sent to Solomon, saying, I have heard the message which thou hast sent unto me: I will do all thy desire concerning timber of cedar, and concerning timber of fir.

So Hiram gave Solomon timber of cedar and timber of fir according to all his desire.

And he built the walls of the house within with boards of cedar: from the floor of the house unto the walls of the ceiling, he covered them on the inside with wood; and he covered the floor of the house with boards of fir.
