2 Chronicles 30:18-20

MKJV(i) 18 For many of the people, many from Ephraim and Manasseh, Issachar and Zebulun, had not been cleansed, but ate the Passover otherwise than it was written. But Hezekiah prayed for them, saying, May the good LORD pardon everyone 19 who prepares his heart to seek God, Jehovah, the God of his fathers, though not cleansed according to the purification of the sanctuary. 20 And Jehovah listened to Hezekiah and healed the people.
