1 Chronicles 24:4-5

4There were more leaders found of the sons of Eleazar than of the sons of Ithamar, and thus they were divided. Among the sons of Eleazar were sixteen heads of their fathers’ houses, and eight heads of their fathers’ houses among the sons of Ithamar.

5Thus they were divided by lot, one group as another, for there were officials of the sanctuary and officials of the house of God, from the sons of Eleazar and from the sons of Ithamar.
