2 Chronicles 29:5

5 and said to them, Sons of Levi, hear ye me, and be ye hallowed; cleanse ye the house of the Lord God of your fathers; and do ye away all uncleanness from the saintuary. (and said to them, Sons of Levi/Levites, listen ye to me, and be ye consecrated, or purified, now; and cleanse ye the House of the Lord God of your fathers; and do ye away all uncleanness from the sanctuary.)

2 Chronicles 29:5 Meaning and Commentary

2 Chronicles 29:5

And said unto them, hear me, ye Levites; sanctify yourselves,
&c.] By washing their bodies and their garments, that no pollution might attend them in their service, see ( Isaiah 52:11 )

and sanctify the house of the Lord God of your fathers;
by carrying out of it all manner of uncleanness, as they did, ( 2 Chronicles 29:16 ) ,

and carry forth the filthiness out of the holy place;
or the abomination; the altar, like that at Damascus, which Ahaz, removing the altar of the Lord, had placed in the court of the priests; or, as Kimchi thinks, an idol, which he had set upon that altar.

2 Chronicles 29:5 In-Context

3 In that year, and in the first month of his realm, he opened the gates of the house of the Lord, and restored, or repaired, those gates;

4 and he brought (in) the priests, and deacons (and the Levites), and he gathered them together into the east street,

5 and said to them, Sons of Levi, hear ye me, and be ye hallowed; cleanse ye the house of the Lord God of your fathers; and do ye away all uncleanness from the saintuary. (and said to them, Sons of Levi/Levites, listen ye to me, and be ye consecrated, or purified, now; and cleanse ye the House of the Lord God of your fathers; and do ye away all uncleanness from the sanctuary.)

6 Our fathers have sinned, and done evil in the sight of the Lord our God, and forsook him; they turned away their faces from the tabernacle of the Lord our God, and gave their back (and they turned their backs on him).

7 They closed the doors that were in the porch (They closed the doors of the vestibule), and quenched the lanterns; and they burnt not incense, and they offered not burnt sacrifices in the saintuary of (the) God of Israel.
