2 Chronicles 30:18-20

18For 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 was written. But Hezekiah prayed for them, saying, The good Yhwh pardon every one

19That prepareth his heart to seek God, Yhwh God of his fathers, though he be not cleansed according to the purification of the sanctuary.

20And Yhwh hearkened to Hezekiah, and healed the people.
