'Families of the Earth' in the Bible

I will bless those who bless you, but the one who treats you lightly I must curse, and all the families of the earth will bless one another by your name."

Your descendants will be like the dust of the earth, and you will spread out to the west, east, north, and south. All the families of the earth will pronounce blessings on one another using your name and that of your descendants.
