1 Chronicles 24:3-19

³ With the help of Zadok, who was a descendant of Eleazar, and of Ahimelech, who was a descendant of Ithamar, David divided Aaron's descendants into groups according to their various duties. ⁴ Eleazar's descendants were divided into sixteen groups and Ithamar's into eight, for there were more family leaders among the descendants of Eleazar. ⁵ All tasks were assigned to the various groups by means of sacred lots so that no preference would be shown, for there were many qualified officials serving God in the sanctuary from among the descendants of both Eleazar and Ithamar. ⁶ Shemaiah son of Nethanel, a Levite, acted as secretary and wrote down the names and assignments in the presence of the king, the officials, Zadok the priest, Ahimelech son of Abiathar, and the family leaders of the priests and Levites. The descendants of Eleazar and Ithamar took turns casting lots. ⁷ The first lot fell to Jehoiarib. The second lot fell to Jedaiah. ⁸ The third lot fell to Harim. The fourth lot fell to Seorim. ⁹ The fifth lot fell to Malkijah. The sixth lot fell to Mijamin. ¹⁰ The seventh lot fell to Hakkoz. The eighth lot fell to Abijah. ¹¹ The ninth lot fell to Jeshua. The tenth lot fell to Shecaniah. ¹² The eleventh lot fell to Eliashib. The twelfth lot fell to Jakim. ¹³ The thirteenth lot fell to Huppah. The fourteenth lot fell to Jeshebeab. ¹⁴ The fifteenth lot fell to Bilgah. The sixteenth lot fell to Immer. ¹⁵ The seventeenth lot fell to Hezir. The eighteenth lot fell to Happizzez. ¹⁶ The nineteenth lot fell to Pethahiah. The twentieth lot fell to Jehezkel. ¹⁷ The twenty-first lot fell to Jakin. The twenty-second lot fell to Gamul. ¹⁸ The twenty-third lot fell to Delaiah. The twenty-fourth lot fell to Maaziah. ¹⁹ Each group carried out its appointed duties in the house of the Lord according to the procedures established by their ancestor Aaron in obedience to the commands of the Lord, the God of Israel.
