'Families of the Earth' in the Bible

And I will bless them that bless you, and curse him that curses you: and in you shall all families of the earth be blessed.

And your descendants shall be as 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 descendants 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, that whosoever will not come up of all the families of the earth unto Jerusalem to worship the King, the LORD of hosts, even upon them shall be no rain.

You are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, And in your descendants shall all the families of the earth be blessed.
