2 Chronicles 30:10-19

10So the posts passed from city to city through the country of Ephraim and Manasseh even to Zebulun: but they laughed them to scorn, and mocked them. 11Nevertheless some from Asher and Manasseh and of Zebulun humbled themselves, and came to Jerusalem. 12Also in Judah the hand of God was to give them one heart to do the commandment of the king and of the princes, by the word of the LORD.

13And there assembled at Jerusalem many people to keep the feast of unleavened bread in the second month, a very great congregation. 14And they arose and took away the altars that were in Jerusalem, and all the altars for incense they took away, and cast them into the brook Kidron. 15Then they killed the passover on the fourteenth day of the second month: and the priests and the Levites were ashamed, and sanctified themselves, and brought in the burnt offerings into the house of the LORD. 16And they stood in their place after their custom, according to the law of Moses the man of God: the priests sprinkled the blood, which they received from the hand of the Levites.1 17For there were many in the congregation that were not sanctified: therefore the Levites had the charge of the killing of the passovers for every one that was not clean, to sanctify them to the LORD. 18For a multitude of the people, even many of Ephraim, and Manasseh, Issachar, and Zebulun, had not cleansed themselves, yet they ate the passover otherwise than it was written. But Hezekiah prayed for them, saying, The good LORD pardon every one 19That prepareth his heart to seek God, the LORD God of his fathers, though he is not cleansed according to the purification of the sanctuary.
