2 Chronicles 29:17 Meaning and Commentary

2 Chronicles 29:17

Now they began on the first day of the first month to
sanctify
Either of the reign of King Hezekiah, or rather of the year; the month Ab or Nisan, as the Targum expresses it: and on the eighth of the month came they to the porch of the Lord;
they seem to have begun cleansing the inner part of the temple first, and so came forward until they came to the porch which led into it: so they sanctified the house of the Lord in eight days;
the holy place, and it may be the most holy place, and the court of the priests: and on the sixteenth day of the first month they made an end;
it took them eight days more to cleanse the outward porch, and the buildings and chambers belonging to the temple; according to Jarchi, it required so much time, because Ahaz had framed pictures of idols upon the walls of the temple, which could not be defaced sooner.

2 Chronicles 29:17 In-Context

15 These Levites gathered their brothers together and made themselves holy for service in the Temple. Then they went into the Temple of the Lord to purify it. They obeyed the king's command that had come from the Lord.

16 When the priests went into the Temple of the Lord to purify it, they took out all the unclean things they found in the Temple of the Lord and put them in the Temple courtyard. Then the Levites took these things out to the Kidron Valley.

17 Beginning on the first day of the first month, they made the Temple holy for the Lord's service. On the eighth day of the month, they came to the porch of the Temple, and for eight more days they made the Temple of the Lord holy. So they finished on the sixteenth day of the first month.

18 Then they went to King Hezekiah and said, "We have purified the entire Temple of the Lord, the altar for burnt offerings and its utensils, and the table for the holy bread and all its utensils.

19 When Ahaz was king, he was unfaithful to God and removed some things from the Temple. But we have put them back and made them holy for the Lord. They are now in front of the Lord's altar."
