2 Chronicles 30:15-18

CLV(i) 15 and they slaughter the passover-offering on the fourteenth of the second month, and the priests and the Levites have been ashamed, and sanctify themselves, and bring in burnt-offerings to the house of Yahweh. 16 And they stand on their station according to their ordinance; according to the law of Moses the man of Elohim the priests are sprinkling the blood out of the hand of the Levites, 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.
