2 Chronicles 30:16-19 New King James Version (NKJV)

16. They stood in their place according to their custom, according to the Law of Moses the man of God; the priests sprinkled the blood received from the hand of the Levites.

17. For there were many in the assembly who had not sanctified themselves; therefore the Levites had charge of the slaughter of the Passover lambs for everyone who was not clean, to sanctify them to the Lord.

18. For a multitude of the people, many from Ephraim, Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the Passover contrary to what was written. But Hezekiah prayed for them, saying, “May the good Lord provide atonement for everyone

19. who prepares his heart to seek God, the Lord God of his fathers, though he is not cleansed according to the purification of the sanctuary.”
