2 Chronicles 30:15-17

30:15 They slaughtered the Passover lamb on the fourteenth day of the second month. The priests and Levites were ashamed, so they consecrated themselves and brought burnt sacrifices to the Lord’s temple. 30:16 They stood at their posts according to the regulations outlined in the law of Moses, the man of God. The priests were splashing the blood as the Levites handed it to them. 30:17 Because many in the assembly had not consecrated themselves, the Levites slaughtered the Passover lambs of all who were ceremonially unclean and could not consecrate their sacrifice to the Lord.

Exodus 12:6

12:6 You must care for it until the fourteenth day of this month, and then the whole community of Israel will kill it around sundown.

Exodus 12:21-22

12:21 Then Moses summoned all the elders of Israel, and told them, “Go and select for yourselves a lamb or young goat for your families, and kill the Passover animals. 12:22 Take a branch of hyssop, dip it in the blood that is in the basin, and apply to the top of the doorframe and the two side posts some of the blood that is in the basin. Not one of you is to go out the door of his house until morning.

Ezra 6:20-21

6:20 The priests and the Levites had purified themselves, every last one, and they all were ceremonially pure. They sacrificed the Passover lamb for all the exiles, for their colleagues the priests, and for themselves. 6:21 The Israelites who were returning from the exile ate it, along with all those who had joined them in separating themselves from the uncleanness of the nations of the land to seek the Lord God of Israel.
