2 Chronicles 30:17-19

ERV(i) 17 For there were many in the congregation that had not sanctified themselves: therefore the Levites had the charge of killing the passovers for every one that was not clean, to sanctify them unto the LORD. 18 For a multitude of the people, even many of Ephraim and Manasseh, Issachar and Zebulun, had not cleansed themselves, yet did they eat the passover otherwise than it is written. For Hezekiah had prayed for them, saying, The good LORD pardon every one 19 that setteth his heart to seek God, the LORD, the God of his fathers, though [he be] not [cleansed] according to the purification of the sanctuary.
