1 Chronicles 24:3-5

Good News Translation

³ King David organized the descendants of Aaron into groups according to their duties. He was assisted in this by Zadok, a descendant of Eleazar, and by Ahimelech, a descendant of Ithamar. ⁴ The descendants of Eleazar were organized into sixteen groups, while the descendants of Ithamar were organized into eight; this was done because there were more male heads of families among the descendants of Eleazar. ⁵ Since there were Temple officials and spiritual leaders among the descendants of both Eleazar and Ithamar, assignments were made by drawing lots.
