2 Chronicles 35:5-6

And stand in the holy place [of the priests] according to the sections of the fathers’ households of your fellow kinsmen the lay people, and according to the Levites, by division of [the families of] a father’s household. Slaughter the Passover lambs and consecrate yourselves, and prepare for your fellow countrymen to carry out (obey) the word of the LORD given by Moses.”
