2 Chronicles 30:16

13 Many people assembled at Jerusalem to keep the feast of unleavened bread in the second month, a very great assembly.

14 They arose and took away the altars that were in Jerusalem, and they took away all the altars for incense and threw them into the brook Kidron.

15 Then they killed the Passover on the fourteenth day of the second month. The priests and the Levites were ashamed, and sanctified themselves, and brought burnt offerings into the LORD’s house.

16 They stood in their place after their order, according to the law of Moses the man of God. The priests sprinkled the blood which they received of the hand of the Levites.

17 For there were many in the assembly who had not sanctified themselves; therefore the Levites were in charge of killing the Passovers for everyone who was not clean, to sanctify them to the LORD.

18 For a multitude of the people, even many of Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the Passover other than the way it is written. For Hezekiah had prayed for them, saying, “May the good LORD pardon everyone

19 who sets his heart to seek God, the LORD, the God of his fathers, even if they aren’t clean according to the purification of the sanctuary.”
