'One Father' in the Bible

Shemaiah, the son of Nethanel the scribe, from the Levites, recorded them in the presence of the king, the princes, Zadok the priest, Ahimelech the son of Abiathar, and the heads of the fathers’ households of the priests and of the Levites; one father’s household taken for Eleazar and one taken for Ithamar.

“Do we not all have one father? Has not one God created us? Why do we deal treacherously each against his brother so as to profane the covenant of our fathers?
