'Cedar tree' in the Bible

And as David dwelt in his house he said to Nathan the prophet, "Lo, I dwell in a house of cedar tree: and the Ark of the LORD's covenant dwelleth under curtains."

Neither in any place wheresoever I have walked throughout all Israel, spake I ever one word to any of the judges of Israel which I commanded to feed my people, saying, 'Why build ye me not a house of Cedar tree?'
