1 Chronicles 24:4-5

4Since more chief men were found from the 1descendants of Eleazar than the 2descendants of Ithamar, they divided them thus: there were sixteen heads of fathers’ households of the 3descendants of Eleazar and eight of the 4descendants of Ithamar, according to their fathers’ households.

55Thus they were divided by lot, the one as the other; for they were officers of the sanctuary and officers of God, both from the 6descendants of Eleazar and the 7descendants of Ithamar.
