'Priests and Levites' in the Bible

And David said to all the congregation of Israel, If it seem good to you, and it be of Jehovah our God, let us send abroad to our brethren everywhere, that are left in all the lands of Israel, and with them to the priests and Levites in their cities and suburbs, that they may gather themselves to us;

And Shemaiah the son of Nethaneel the scribe, one of the Levites, inscribed them before the king, and the princes, and Zadok the priest, and Ahimelech the son of Abiathar, and the chief fathers of the priests and Levites: one father's house was drawn for Eleazar, and one drawn for Ithamar.

These likewise cast lots just as their brethren the sons of Aaron before David the king, and Zadok, and Ahimelech, and the chief fathers of the priests and Levites, the chief fathers just as the youngest of their brethren.
