2 Chronicles 30:15-17

15 cAnd they slaughtered the Passover lamb on the fourteenth day of the second month. dAnd the priests and the Levites were ashamed, eso that they consecrated themselves and brought burnt offerings into the house of the Lord. 16 fThey took their accustomed posts according to the Law of Moses gthe man of God. The priests threw the blood that they received from the hand of the Levites. 17For there were many in the assembly who had not consecrated themselves. Therefore the Levites had to slaughter the Passover lamb for everyone who was not clean, to consecrate it to the Lord.
