2 Chronicles 30:10-19

10And the couriers traveled from city to city through the land of Ephraim and Manasseh as far as Zebulun, but the people scorned and mocked them. 11Nevertheless, some from Asher, Manasseh, and Zebulun humbled themselves and came to Jerusalem. 12Moreover, the power of God was on the people in Judah to give them one heart to obey the command of the king and his officials according to the word of the LORD.

13In the second month, a very great assembly gathered in Jerusalem to celebrate the Feast of Unleavened Bread.1 14They proceeded to remove the altars in Jerusalem and to take away the incense altars and throw them into the Kidron Valley. 15And on the fourteenth day of the second month they slaughtered the Passover lamb. The priests and Levites were ashamed, and they consecrated themselves and brought burnt offerings to the house of the LORD.

16They stood at their prescribed posts, according to the Law of Moses the man of God. The priests splattered the blood, which they received from the hand of the Levites. 17Since there were many in the assembly who had not consecrated themselves, the Levites were in charge of slaughtering the Passover lambs for every unclean person to consecrate the lambs to the LORD.

18A large number of the people—many from Ephraim, Manasseh, Issachar, and Zebulun—had not purified themselves, yet they ate the Passover, contrary to what was written. But Hezekiah interceded for them, saying, “May the LORD, who is good, provide atonement for everyone 19who sets his heart on seeking God—the LORD, the God of his fathers—even if he is not cleansed according to the purification rules of the sanctuary.”
