2 Chronicles 5:7-10
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.
11-13The priests then left the Holy Place. All the priests there were consecrated, regardless of rank or assignment; and all the Levites who were musicians were there—Asaph, Heman, Jeduthun, and their families, dressed in their worship robes; the choir and orchestra assembled on the east side of the Altar and were joined by 120 priests blowing trumpets. The choir and trumpets made one voice of praise and thanks to God—orchestra and choir in perfect harmony singing and playing praise to God:
Yes! God is good! His loyal love goes on forever!
