2 Chronicles 5:4-6
4-6When all the leaders of Israel were ready, the Levites took up the Chest. They carried the Chest, the Tent of Meeting, and all the sacred things in the Tent used in worship. The priests, all Levites, carried them. King Solomon and the entire congregation of Israel were there before the Chest, worshiping and sacrificing huge numbers of sheep and cattle—so many that no one could keep track.
7-10The priests brought the Chest of the Covenant of God to its place in the Inner Sanctuary, the Holy of Holies, under the wings of the cherubim. The outspread wings of the cherubim formed a canopy over the Chest and its poles. The ends of the poles were so long that they stuck out from the entrance of the Inner Sanctuary, but were not noticeable further out—they're still there today. There was nothing in the Chest itself but the two stone tablets that Moses had placed in it at Horeb where God made a covenant with Israel after bringing them up from Egypt.
