'Households' in the Bible

These {mentioned by name} [were] leaders in their families, and their fathers' households increased greatly.

And their kinsmen according to their fathers' households: Michael, Meshullam, Sheba, Jorai, Jacan, Zia, and Eber, seven.

Ahi son of Abdiel, son of Guni, [was] chief in their fathers' households.

Now these [were] the heads of their fathers' households: Epher, Ishi, Eliel, Azriel, Jeremiah, Hodaviah, and Jahdiel, mighty men of strength, {famous men}, heads of their fathers' households.
