1 Chronicles 24:5-6

5Thus, they were impartially divided by lot for there were officials of the Holy Place and officials of God, both from the sons of Eleazar and from the sons of Ithamar.

6The scribe Shemaiah, son of Nethanel from the Levites, recorded them in the presence of the king, the princes, Zadok the priest, Ahimelech son of Abiathar, and the leaders of the clans of the kohanim and of the Levites: one clan taken for Eleazar and one for Ithamar.
