"“It came even to pass, as 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 endureth forever: that then the house was filled with a cloud, even the house of the Lord; so that the priests could not stand to minister by reason of the cloud: for the glory of the Lord had filled the house of God.” Verses 13, 14 . PK 38.3"
The EGW passage directly quotes 2 Chronicles 5:13-14, which itself contains the phrase from Psalm 136:1. The connection is direct and significant.
