1 Crônicas 24

4And there were more chief men found of the sons of Eleazar than of the sons of Ithamar; and thus were they divided. Among the sons of Eleazar there were sixteen chief men of the house of their fathers, and eight among the sons of Ithamar according to the house of their fathers.
19These were the orderings of them in their service to come into the house of the LORD , according to their manner, under Aaron their father, as the LORD God of Israel had commanded him.
