4 And there were found the sons of Eleazar more chiefs of the mighty ones, than of the sons of Ithamar: and he divided them, sixteen heads of families to the sons of Eleazar, eight according to families to the sons of Ithamar.

5 And he divided them according to their lots, one with the other; for there were those who had charge of the holy things, and those who had charge of the of the Lord among the sons of Eleazar, and among the sons of Ithamar.
