Charles Ellicott Commentary 2 Chronicles 29:18

"Then they went in to Hezekiah the king within [the palace], and said, We have cleansed all the house of Jehovah, and the altar of burnt-offering, with all the vessels thereof, and the table of showbread, with all the vessels thereof." — 2 Chronicles 29:18 (ASV)

They went in. — Heb., into the interior (pĕnîmah, “inner part,” 2 Chronicles 29:16) of the palace.

Hezekiah. — Hizkiyahu. So also in 2 Chronicles 29:27; but in 2 Chronicles 29:30, Yehizkiyahu. (See Note on 2 Chronicles 29:1.)

The altar of burnt offering. — Which Ahaz appears to have superseded (2 Kings 16:14–15), besides removing it from its legal position.

And the shewbread table. — Literally, the table of the pile (of sacred cakes). Only one table is here mentioned. (Compare 1 Chronicles 28:16; 2 Chronicles 4:8; 2 Chronicles 4:19.) The metalwork of all the sacred apparatus would be greatly tarnished, if only from neglect, apart from wanton ill usage.
