1 Chronicles 24:5-6

They divided them by lot, all alike, for there were sacred officers and officers of God among both the sons of Eleazar and the sons of Ithamar. And the scribe Shemaiah, the son of Nethanel, a Levite, recorded them in the presence of the king and the princes and Zadok the priest and Ahimelech the son of Abiathar and the heads of the fathers’ houses of the priests and of the Levites, one father’s house being chosen for Eleazar and one chosen for Ithamar.
