Charles Ellicott Commentary 2 Chronicles 29:7

"Also they have shut up the doors of the porch, and put out the lamps, and have not burned incense nor offered burnt-offerings in the holy place unto the God of Israel." — 2 Chronicles 29:7 (ASV)

The porch. —Of the holy place, or nave of the Temple; the only entrance to the two holy chambers.

Put out the lamps. —Of the great golden stand, in the holy place.

Have not burned incense. —On the golden altar. Literally, And incense they have not burned, and burnt offering they have not offered in the sanctuary. The sanctuary is not the holy place, or larger chamber of the Temple, but it includes the whole sacred precincts, courts as well as buildings. The burnt offerings presented on the new Syrian altar of Ahaz (2 Kings 16:15) are here counted as nothing, because they were irregular (Compare also to 2 Kings 16:14).
