'Household' in the Bible

Then all the people departed each to his house, and David returned to bless his household.

David said to God, “Is it not I who commanded to count the people? Indeed, I am the one who has sinned and done very wickedly, but these sheep, what have they done? O Lord my God, please let Your hand be against me and my father’s household, but not against Your people that they should be plagued.”

Jahath was the first and Zizah the second; but Jeush and Beriah did not have many sons, so they became a father’s household, one class.

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.
