'Priests and Levites' in the Bible

David said to all the assembly of Israel, “If it seems good to you, and if it is from the Lord our God, let us send word everywhere to our fellow countrymen who remain in all the land of Israel, and to the priests and Levites who are with them in their cities with pasture lands, so that they may meet with us;

And he assembled together all the leaders of Israel with the priests and Levites.

Shemaiah, the son of Nethanel the scribe, from the Levites, recorded them in the presence of the king, the officers, Zadok the priest, Ahimelech the son of Abiathar [the priest who escaped Saul’s massacre at Nob], and the heads of the fathers’ households of the priests and of the Levites; one father’s household taken for Eleazar and one taken for Ithamar.

These also cast lots as did their relatives the sons of Aaron in the presence of David the king, Zadok, Ahimelech, and the heads of the fathers’ households of the priests and of the Levites—the head of father’s households as well as those of his younger brother.

And see, [you have] the divisions of the priests and Levites for all the service of God’s house, and every willing, skillful man will be with you in all the kinds of work for any kind of service. Also the officers and all the people will be entirely at your command.”
