2 Samuel 7:2

that the king said unto Nathan, the prophet, whom he regarded highly as a confidential adviser, See, now, I dwell in an house of cedar, in a fine palace, but the ark of God dwelleth within curtains. Even though David had provided a tabernacle in his city which consisted of very fine and costly curtains, like those of the first Tabernacle, yet the contrast was too obvious and too incongruous; it did not seem right and fitting to David that he should have a finer palace than that used for housing the ark.
