2 Chronicles 30:17-19

CLV(i) 17 for many [are] in the assembly who have not sanctified themselves, and the Levites [are] over the slaughtering of the passover-offerings for every one not clean, to sanctify [him] to Yahweh. 18 for a multitude of the people, many from Ephraim and Manasseh, Issachar, and Zebulun, have not been cleansed, but have eaten the passover otherwise than it is written; but Hezekiah prayed for them, saying, `Yahweh, who [is] good, does receive atonement for every on. 19 who has prepared his heart to seek Elohim--Yahweh, Elohim of his fathers--yet not according to the cleansing of the sanctuary;.
