2 Samuel 7:2
2. the king said unto Nathan the prophet, See now, I dwell in an house of cedar—The palace which Hiram had sent men and materials to build in Jerusalem had been finished. It was magnificent for that age, though made wholly of wood: houses in warm countries not being required to possess the solidity and thickness of walls which are requisite for dwellings in regions exposed to rain and cold. Cedar was the rarest and most valuable timber. The elegance and splendor of his own royal mansion, contrasted with the mean and temporary tabernacle in which the ark of God was placed, distressed the pious mind of David.
2 Samuel 7:6-7
4-17. it came to pass that night, that the word of the Lord came unto Nathan—The command was given to the prophet on the night immediately following; that is, before David could either take any measures or incur any expenses.
1 Kings 5:14
1 Kings 6:15-18
15-21. he built the walls of the house within—The walls were wainscotted with cedar-wood; the floor, paved with cypress planks; the interior was divided (by a partition consisting of folding doors, which were opened and shut with golden chains) into two apartments—the back or inner room, that is, the most holy place, was twenty cubits long and broad; the front, or outer room, that is, the holy place, was forty cubits. The cedar-wood was beautifully embellished with figures in relievo, representing clusters of foliage, open flowers, cherubims, and palm trees. The whole interior was overlaid with gold, so that neither wood nor stone was seen; nothing met the eye but pure gold, either plain or richly chased.
