2 Chronicles 30
17 Ref For there were still a number of the people there who had not made themselves holy: so the Levites had to put Passover lambs to death for those who were not clean, to make them holy to the Lord.
18 Ref For a great number of the people from Ephraim and Manasseh, Issachar and Zebulun, had not made themselves clean, but they took the Passover meal, though not in the right way. For Hezekiah had made prayer for them, saying, May the good Lord have mercy on everyone
19 Ref Who, with all his heart, is turned to God the Lord, the God of his fathers, even if he has not been made clean after the rules of the holy place.
