'Cedar beams' in the Bible

He built the inner court with three courses of cut stone, and a course of cedar beams.

For he built the house of the forest of Lebanon; its length was one hundred cubits, and its breadth fifty cubits, and its height thirty cubits, on four rows of cedar pillars, with cedar beams on the pillars.

The great court around had three courses of cut stone, and a course of cedar beams; like as the inner court of the house of Yahweh, and the porch of the house.
