2 Chronicles 30:17-20

17Many people in the assembly had not made themselves holy. So the Levites had to kill the Passover lambs for all who weren’t clean  and couldn’t make their lambs holy for the Lord.

18Many people from Ephraim, Manasseh, Issachar, and Zebulun had not made themselves clean. So they ate the Passover, but not in the way the written instructions said they should. Hezekiah prayed for them: “May the good Lord forgive

19those who have their hearts set on dedicating their lives to serving God. May the Lord God of their ancestors do this for those who are not clean as required for the holy place.”

20The Lord listened to Hezekiah and healed the people.
