2 Chronicles 30:18-20

Leeser(i) 18 For a large portion of the people, even many out of Ephraim, and Menasseh, Issachar, and Zebulun, had not cleansed themselves, but ate the passover not as it is written. However Hezekiah prayed for them, saying, The Lord who is good will grant pardon for this. 19 To every one that hath directed his heart to seek God, the Lord the God of his fathers; though he be not cleansed according to the purification of the sanctuary. 20 And the Lord hearkened to Hezekiah, and he healed the people.
