2 Chronicles 30:15-19

LXX2012(i) 15 Then they killed the passover on the fourteenth day of the second month: and the priests and the Levites repented, and purified [themselves], and brought whole burnt offerings into the house of the Lord. 16 And they stood at their post, according to their ordinance, according to the commandment of Moses the man of God: and the priests received the blood from the hand of the Levites. 17 For a great part of the congregation was not sanctified; and the Levites were [ready] to kill the passover for every one who could not sanctify himself to the Lord. 18 For the greatest part of the people of Ephraim, and Manasse, and Issachar, and Zabulon, had not purified [themselves], but ate the passover contrary to the scripture. On this account also Ezekias 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.
