2 Chronicles 30:15-17

ASV(i) 15 Then they killed the passover on the fourteenth [day] of the second month: and the priests and the Levites were ashamed, and sanctified themselves, and brought burnt-offerings into the house of Jehovah. 16 And they stood in their place after their order, according to the law of Moses the man of God: the priests sprinkled the blood [which they received] of the hand of the Levites. 17 For there were many in the assembly that had not sanctified themselves: therefore the Levites had the charge of killing the passovers for every one that was not clean, to sanctify them unto Jehovah.
