Kings III 8:8-11

⁸And the holy staves projected, and the ends of the holy staves appeared out of the holy places in front of the oracle, and were not seen without.

⁹There was nothing in the ark except the two tables of stone, the tables of the covenant which Moses put there in Choreb, which tables the Lord made as a covenant with the children of Israel in their going forth from the land of Egypt.

¹⁰And it came to pass when the priests departed out of the holy place, that the cloud filled the house.

¹¹And the priests could not stand to minister because of the cloud, because the glory of the Lord filled the house.
