2 Chronicles 30:15

2 Chronicles 30:15 Meaning and Commentary

2 Chronicles 30:15

Then they killed the passover on the fourteenth day of the
second month
For though they could not keep it in the month in which it should have been kept, for the reasons before given, yet they kept it on the day of the month in which it was observed:

and the priests and the Levites were ashamed;
of their negligence and backwardness to service, and to fit themselves for it, when they saw the people so forward and ready to attend to it:

and they sanctified themselves;
by washing their bodies and their garments:

and brought in the burnt offerings into the house of the Lord;
to be offered up on the altar of burnt offerings, to expiate their own sins, and the sins of the people; though some take these to be the passover offerings; but they were not offered until the fifteenth day, and besides were peace offerings, mentioned ( 2 Chronicles 30:22 ) , rather these were the daily sacrifices.

2 Chronicles 30:15 In-Context

13 It turned out that there was a tremendous crowd of people when the time came in the second month to celebrate the Passover (sometimes called the Feast of Unraised Bread).

14 First they went to work and got rid of all the pagan altars that were in Jerusalem - hauled them off and dumped them in the Kidron Valley.

15 Then, on the fourteenth day of the second month, they slaughtered the Passover lambs. The priests and Levites weren't ready; but now, embarrassed in their laziness, they consecrated themselves and brought Whole-Burnt-Offerings to The Temple of God.

16 Ready now, they stood at their posts as designated by The Revelation of Moses the holy man; the priests sprinkled the blood the Levites handed to them.

17 Because so many in the congregation had not properly prepared themselves by consecration and so were not qualified, the Levites took charge of the slaughter of the Passover lambs so that they would be properly consecrated to God.
