Lots of people will be born into your family, and they will become a really big mob of people. There will be lots and lots of them, just like there are lots of little bits of dirt on the ground. And those people in your family, they will spread out a long way, and they will live in lots of different places. Some of them will go west, some of them will go east, some of them will go north, and some of them will go south. And I will use your family to do good things for all the families in the world.
