Bible Verses About Priests: Divided by David into twenty-four courses

The divisions of the descendants of Aharon were as follows: The sons of Aharon: Nadav, Avihu, El'azar and Itamar.

But Nadav and Avihu died before their father and had no children; therefore El'azar and Itamar functioned as the cohanim.

David, together with Tzadok from the descendants of El'azar, and Achimelekh from the descendants of Itamar, arranged them in divisions for service.

There were more men who were chiefs found among the descendants of El'azar than among the descendants of Itamar; therefore there were sixteen divisions of the descendants of El'azar, headed by clan leaders, and eight divisions of the descendants of Itamar, according to their clans.

They were assigned [periods of service] by lot, the one group equally with the other, since both the descendants of El'azar and the descendants of Itamar had officers of the sanctuary and officers of God.

Sh'ma'yah the son of N'tan'el the secretary, one of the L'vi'im, recorded them in the presence of the king, the officers, Tzadok the cohen, Achimelekh the son of Evyatar, and the clan leaders of the cohanim and of the L'vi'im - with two clan divisions taken from El'azar for each one from Itamar.

The first lot drawn was for Y'hoyariv, the second for Y'da'yah,

the third for Harim, the fourth for S'orim,

the fifth for Malkiyah, the sixth for Miyamin,

the seventh for Hakotz, the eighth for Aviyah,

the ninth for Yeshua, the tenth for Sh'khanyahu,

the eleventh for Elyashiv, the twelfth for Yakim,

the thirteenth for Hupah, the fourteenth for Yeshev'av,

the fifteenth for Bilgah, the sixteenth for Immer,

the seventeenth for Hezir, the eighteenth for HaPitzetz

the nineteenth for P'tachyah, the twentieth for Yechezk'el,

the twenty-first for Yakhin, the twenty-second for Gamul,

the twenty-third for D'layahu, and the twenty-fourth for Ma'azyahu.

These are the divisions and the sequence in which they served in the house of ADONAI, in accordance with the rule they were given through Aharon their ancestor, as ADONAI the God of Isra'el had ordered him.

As David his father had ordered, he appointed the divisions of the cohanim for their service and the L'vi'im to their tasks - to praise and to perform their service in the presence of the cohanim according to each day's requirements. He also appointed the gatekeepers by their divisions to be at every gate, for David the man of God had so ordered.

Organize yourselves by clans and duty divisions according to the arrangement written down by David king of Isra'el and Shlomo his son.

Stand in the Holy Place according to the divisions of the clans of your kinsmen the ordinary people, with part of a clan of L'vi'im serving each clan [of Isra'el].
