'Priests and Levites' in the Bible

And David said unto all the congregation of Israel, If it seem good unto you, and that it be of the LORD our God, let us send abroad unto our brethren every where, that are left in all the land of Israel, and with them also to the priests and Levites which are in their cities and suburbs, that they may gather themselves unto us:

The priests and Levites consecrated themselves so they could bring up the ark of the Lord God of Israel.

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

And Shemaiah the son of Nethaneel the scribe, one of the Levites, wrote them before the king, and the princes, 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 being taken for Eleazar, and one taken for Ithamar.

These likewise cast lots over against their brethren the sons of Aaron in the presence of David the king, and Zadok, and Ahimelech, and the chief of the fathers of the priests and Levites, even the principal fathers over against their younger brethren.

And for the divisions of the priests and Levites, and for all the work in connection with the worship of the house of the Lord, and all the vessels used in the house of the Lord;

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.”
