The Ark Enters the Temple

"And all the elders of Israel came; and the Levites took up the ark." "There was nothing in the ark save the two tables which Moses put therein at Horeb."

"Also the Levites which were the singers, all of them of Asaph, of Heman, of Jeduthun… being arrayed in white linen, having cymbals and psalteries and harps, stood at the east end of the altar, and with them an hundred and twenty priests sounding with trumpets."

"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… saying, For he is good; for his mercy endureth for ever: that then the house was filled with a cloud… for the glory of the LORD had filled the house of God."

Music and glory

1 Kings 8:10–11 says the cloud filled the house when the priests came out. Chronicles adds that it happened at the moment the Levite choir and priestly trumpets praised God in unison. In Chronicles worship is where God's presence is experienced.

The ark's contents

Hebrews 9:4 lists the golden pot of manna and Aaron's rod with the tablets in the ark. Kings and Chronicles say only the tablets were inside "at that time." A comparison between texts, not a manuscript problem.
