'Families of the Earth' in the Bible

And I will bless those that bless you and curse the one who curses you. And in you shall all families of the earth be blessed.

And your seed shall be like the dust of the earth, and you shall spread abroad to the west, and to the east, and to the north, and to the south. And in you and in your Seed shall all the families of the earth be blessed.

You only have I known of all the families of the earth; therefore I will punish you for all your iniquities.

And it shall be, whoever will not come up from all the families of the earth to Jerusalem to worship the King, Jehovah of Hosts, even on them shall be no rain.
