'Priests and Levites' in the Bible

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

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 they departed not from the commandment of the king to the priests and Levites concerning any matter, or concerning the treasures.

And Hezekiah appointed the courses of the priests and the Levites after their courses, every man according to his service, the priests and Levites for burnt-offerings and for peace-offerings, to minister, and to give thanks, and to praise in the gates of the tents of the LORD.

But many of the priests and Levites and chief of the fathers, old men, that had seen the first house, when the foundation of this house was laid before their eyes, wept with a loud voice; and many shouted aloud for joy:

I make a decree, that all they of the people of Israel, and of his priests and Levites, in my realm, who are disposed of their own free will to go to Jerusalem, go with thee.

Also we certify you, that concerning any of the priests and Levites, singers, porters, Nethinims, or ministers of this house of God, it shall not be lawful to impose toll, tribute, or custom upon them.

And at that time were some appointed over the chambers for the treasures, for the offerings, for the first-fruits, and for the tithes, to gather into them out of the fields of the cities the portions of the law for the priests and Levites: for Judah rejoiced for the priests and for the Levites that waited.

And this is the testimony of John, when the Jews sent priests and Levites from Jerusalem, to ask him, Who art thou?
