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 Ch2 30:22, rather these were the daily sacrifices.
