'Priests and Levites' in the Bible

And David said to all the congregation of Israel, If it is good to you, and if it has broken forth from Jehovah our God, let us send to our brothers, those remaining in all the lands of Israel, and with them to the priests and Levites in their cities that they be gathered to us.

And Shemaiah the son of Nethaneel the scribe, of the Levites, wrote them before the king, and the rulers, and Zadok the priest, and Ahimelech the son of Abiathar, and before the chief of the fathers of the priests and Levites. One principal household was taken for Eleazar, and one taken for Ithamar.

And they also cast lots along with their brothers, the sons of Aaron, before David the king, and Zadok, and Ahimelech, and the chief of the fathers of the priests and Levites, the head of the fathers, as well as his younger brother.
