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.

15 They gathered their brothers together, consecrated themselves, and went according to the king's command by the words of the Lord to cleanse the Lord's temple.

16 The priests went to the entrance of the Lord's temple to cleanse it. They took all the detestable things they found in the Lord's sanctuary to the courtyard of the Lord's temple. Then the Levites received them and took them outside to the Kidron Valley.

18 Then they went inside to King Hezekiah and said, "We have cleansed the whole temple of the Lord, the altar of burnt offering and all its utensils, and the table for the rows [of the bread of the Presence] and all its utensils.

19 All the utensils that King Ahaz rejected during his reign when he became unfaithful we have set up and consecrated. They are in front of the altar of the Lord."
