2 Chronicles 30:13-19

In the second month a large crowd came together in Jerusalem to celebrate the Feast of Unleavened Bread. The people removed the altars and incense altars to gods in Jerusalem and threw them into the Kidron Valley. They killed the Passover lamb on the fourteenth day of the second month. The priests and the Levites were ashamed, so they made themselves holy and brought burnt offerings into the Temple of the LORD. They took their regular places in the Temple as the Teachings of Moses, the man of God, commanded. The Levites gave the blood of the sacrifices to the priests, who sprinkled it on the altar. Since many people in the crowd had not made themselves holy, the Levites killed the Passover lambs for everyone who was not clean. The Levites made each lamb holy for the LORD. Although many people from Ephraim, Manasseh, Issachar, and Zebulun had not purified themselves for the feast, they ate the Passover even though it was against the law. So Hezekiah prayed for them, saying, “LORD, you are good. You are the LORD, the God of our ancestors. Please forgive all those who try to obey you even if they did not make themselves clean as the rules of the Temple command.”
