2 Chronicles 30:17-21

For there were many in the assembly who had not consecrated themselves; therefore, the Levites were in charge of the slaughter of the Passover lambs for everyone who was unclean, in order to consecrate them to the Lord.

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

everyone who prepares his heart to seek God, the Lord God of his fathers, though not according to the purification rules of the sanctuary.”

So the Lord heard Hezekiah and healed the people.

The sons of Israel present in Jerusalem celebrated the Feast of Unleavened Bread for seven days with great joy, and the Levites and the priests were praising the Lord day after day with loud instruments to the Lord.
