The divisions of the descendants of Aaron were as follows: Aaron’s sons 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.
Together with Zadok from the descendants of Eleazar and Ahimelech from the descendants of Ithamar, David divided them according to the assigned duties of their service.
They were assigned by lot, for there were officers of the sanctuary and officers of God among both Eleazar’s and Ithamar’s descendants.
These had their assigned duties for service when they entered the LORD’s temple, according to their regulations, which they received from their ancestor Aaron, as the LORD God of Israel had commanded him.
