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 A great number of people gathered in Jerusalem in the second month to celebrate the Festival of Unleavened Bread.
14 They took all the altars that had been used in Jerusalem for offering sacrifices and burning incense and threw them into Kidron Valley.
15 And on the fourteenth day of the month they killed the lambs for the Passover sacrifice. The priests and Levites who were not ritually clean became so ashamed that they dedicated themselves to the Lord, and now they could sacrifice burnt offerings in the Temple.
16 They took their places in the Temple according to the instructions in the Law of Moses, the man of God. The Levites gave the blood of the sacrifices to the priests, who sprinkled it on the altar.
17 Because many of the people were not ritually clean, they could not kill the Passover lambs, so the Levites did it for them and dedicated the lambs to the Lord.
