Divrey Hayamim Bais 30:15

Divrey Hayamim Bais 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.

Divrey Hayamim Bais 30:15 In-Context

13 And there assembled at Yerushalayim Am Rav (Much People) to keep Chag HaMatzot in the second month, a kahal larov me’od (a very great congregation).

14 And they arose and removed the mizbechot that were in Yerushalayim, and all the incense altars they took away, and threw them into the Wadi Kidron.

15 Then they slaughtered the Pesach on the fourteenth day of the second month; and the Kohanim and the Levi’im were ashamed, and they set themselves apart as kodesh, and brought olot to the Beis Hashem.

16 And they stood in their place after their prescribed manner, according to the Torat Moshe Ish HaElohim; the Kohanim sprinkled the dahm, which they received of the yad of the Levi’im.

17 For there were rabbim in HaKahal that were not set apart as kodesh; therefore the Levi’im had the charge of the shechitah (ritual slaughter) of the Pesachim for every one that was not tahor and therefore could not set them apart as kodesh unto Hashem.
