2 Chronicles 30:18-19

CAB(i) 18 For the greatest part of the people of Ephraim, Manasseh, Issachar, and Zebulun, had not purified themselves, but ate the Passover contrary to the Scripture. On this account also Hezekiah prayed concerning them, saying, 19 The good Lord be merciful with regard to every heart that sincerely seeks the Lord God of their fathers, and is not purified according to the purification of the sanctuary.
