Charles Ellicott Commentary 2 Chronicles 7:2

"And the priests could not enter into the house of Jehovah, because the glory of Jehovah filled Jehovah`s house." — 2 Chronicles 7:2 (ASV)

And the priests could not enter into the house of the Lord. —Hardly a different assertion from that of 2 Chronicles 5:14 (“ the priests could not stand to minister ”); the cause in both instances being the same, and expressed in the same words (1 Kings 8:11). But it is quite plain that the writer intends to record in 2 Chronicles 5:7 two distinct appearances of the Divine glory, one before and one after the Prayer of Consecration, both of which were attended by the same effects upon the ministering priests.
