2 Chronicles 5:13-14. [I]ndeed it came to pass, when the trumpeters and singers were as one, to make one sound to be heard in praising and thanking the LORD, and when they lifted up their voice with the trumpets and cymbals and instruments of music, and praised the LORD, saying: “For He is good, for His mercy endures forever,” that the house, the house of the LORD, was filled with a cloud, so that the priests could not continue ministering because of the cloud; for the glory of the LORD filled the house of God.
In this instance, the musicians and singers entered into such a spirit of worship that they became as one. The glory of the Lord actually appeared unto them as a cloud and filled the house of the Lord with His presence.
What a vivid demonstration of the truth recorded in Psalm 22:3 that God is enthroned upon and inhabits the praises of His people!
In John 4:24, Jesus said that those who worship God, must worship Him in spirit and truth. That’s the only kind of worship that brings the glory of God into manifestation!
