'One Father' in the Bible

And Jahath was the chief, and Zizah the second: but Jeush and Beriah had not many sons; therefore they were in one reckoning, as one father's house.

And Shemaiah the son of Nethanel the scribe, one of the Levites, wrote them down before the king, and the leaders, and Zadok the priest, and Ahimelech the son of Abiathar, and before the heads of the fathers' houses of the priests and Levites: one father's house being taken for Eleazar, and one taken for Ithamar.
