2 Chronicles 7:6
The priests stood at their posts, as did the Levites with the musical instruments of the LORD, which King David had made for giving thanks to the LORD and with which David had offered praise, saying, “For His loving devotion endures forever.” Across from the Levites, the priests sounded trumpets, and all the Israelites were standing.
