'Individuals' in the Bible

These were the Levites by their fathers’ households, the heads of the fathers’ households of those registered, according to the number of names of the individuals who were the servants of the house of the Lord, from twenty years old and upward.

These individuals also cast lots corresponding to their relatives, Aaron's descendants, in the presence of King David, Zadok, and Ahimelech, and in the presence of the heads of the ancestral households of the priests and of the descendants of Levi, and the eldest was treated as impartially as was the younger brother.
