Divrey Hayamim Bais 29:16 Meaning and Commentary

2 Chronicles 29:16

And the priests went into the inner part of the house of the
Lord, to cleanse it
Into the holy place, where the candlesticks and shewbread tables stood, into which none but priests might enter, but not into the most holy place, the innermost of all; for none but the high priest might go into that, and only on the day of atonement; though in case of necessity, as for repairs, others might go into it, and so perhaps now to cleanse it, if any pollution was there: and brought out all the uncleanness that they found in the temple of
the Lord into the court of the house of the Lord;
into the court of the priests, where the Levites might be, and were: and the Levites took it, to carry it out abroad into the brook Kidron;
which ran through the valley of the son of Hinnom, into which all unclean things, and the filth of the temple and sacrifices, were usually carried and cast, see ( 2 Kings 18:12 ) .

Divrey Hayamim Bais 29:16 In-Context

14 And of the Bnei Heman, Yechiel, and Shimei; and of the Bnei Yedutun, Shemayah, and Uzziel.

15 And they gathered their achim, and set themselves apart as kodesh, and went in, according to the mitzvat HaMelech, by the words of Hashem, to make tahor the Beis Hashem.

16 And the Kohanim went into the penimah (inner part) Beis Hashem, to make it tahor, and brought out all tumah that they found in the Heikhal Hashem into the khatzer (courtyard) of the Beis Hashem. And the Levi’im took it, to carry it outside into the Wadi Kidron.

17 Now they began on the first day of the chodesh harishon to set apart as kodesh, and on the eighth day of the month they came to the Ulam Hashem; so they set apart as kodesh the Beis Hashem in eight days; and in the sixteenth day of the first month they finished.

18 Then they went penimah to Chizkiyah HaMelech, and said, We have made tahor all the Beis Hashem, and the Mizbe’ach HaOlah, with all the vessels thereof, and the Shulchan HaMa’arechet (Table of the Stacks of Showbread), with all the vessels thereof.
