2 Chronicles 30:15-19

Thomson(i) 15 they killed the paschal lamb on the fourteenth of the second month. And as the priests and the Levites were humbled, and had purified themselves, they offered whole burnt offerings in the house of the Lord, 16 and stood in their station according to the disposition made of them by the command of Moses, the man of God; and the priests received the blood from the hands of the Levites. 17 Because there were many of the congregation who were not purified, therefore the Levites had it in charge to kill the paschal lamb, for every one who had not been able to purify himself to the Lord. 18 And because most of the people from Ephraim, and Manasses, and Issachar, and Zabulon, had not purified themselves, but ate the passover contrary to the scripture, therefore Ezekias prayed for them on this account and said, The good Lord make atonement for every heart 19 which hath directed its course to seek the Lord the God of their fathers, although not according to the purification of the sanctuary.
