'Priests and Levites' in the Bible

And David said to all the assembly of Israel, "{If it seems good to you} and before Yahweh our God, {let us send word abroad} to our brothers who remain in all the land of Israel and [to] the priests and Levites with them in the cities with their pasturelands that they might be gathered to us.

And Shemaiah the son of Nethanel, the scribe, from the Levites, recorded them before the king, the princes, Zadok the priest, Ahimelech the son of Abiathar, and the heads of the {families} of the priests and Levites, one father's house drawn by Lot for Eleazar and one drawn by lot for Ithamar.
