'Priests' in the Bible

Now the first inhabitants that dwelt in their possessions in their cities were, the Israelites, the priests, Levites, and the Nethinims.

And of the priests; Jedaiah, and Jehoiarib, and Jachin,

And some of the sons of the priests made the ointment of the spices.

Jehoiada was the leader of [the house of] Aaron, and with him were 3,700,

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:

And David called for Zadok and Abiathar the priests, and for the Levites, for Uriel, Asaiah, and Joel, Shemaiah, and Eliel, and Amminadab,

So the priests and the Levites sanctified themselves to bring up the ark of the LORD God of Israel.

And Shebaniah, and Jehoshaphat, and Nethaneel, and Amasai, and Zechariah, and Benaiah, and Eliezer, the priests, did blow with the trumpets before the ark of God: and Obededom and Jehiah were doorkeepers for the ark.

Benaiah also and Jahaziel the priests with trumpets continually before the ark of the covenant of God.

And Zadok the priest, and his brethren the priests, before the tabernacle of the LORD in the high place that was at Gibeon,

And Zadok the son of Ahitub, and Abimelech the son of Abiathar, were the priests; and Shavsha was scribe;

And he gathered together all the princes of Israel, with the priests and the Levites.

For their duty is to assist [the priests] the sons of Aaron in the service of the house of the Lord, in [caring for] the courtyards, the chambers, the purifying of all holy things, and any work of the service of the house of God,

The divisions of the descendants of Aaron were these: the sons of Aaron were Nadab, Abihu, Eleazar, and Ithamar.

But Nadab and Abihu died before their father, and they had no sons, so Eleazar and Ithamar served as priests.

Since there were more chief men found among the descendants of Eleazar than among the descendants of Ithamar [because of Eli’s misfortunes, and Saul’s massacre of the priests at Nob], they were divided in this way: sixteen heads of fathers’ households of the descendants of Eleazar and eight of the descendants of Ithamar, corresponding to their fathers’ households.

So they were divided by lot, one group with the other; for they were officers of the sanctuary and officers (high priests) of God, both from the descendants of Eleazar and from the descendants of Ithamar.

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.

Also for the courses of the priests and the Levites, and for all the work of the service of the house of the LORD, and for all the vessels of service in the house of the LORD.

And, behold, the courses of the priests and the Levites, even they shall be with thee for all the service of the house of God: and there shall be with thee for all manner of workmanship every willing skilful man, for any manner of service: also the princes and all the people will be wholly at thy commandment.
