Les explains that after Abraham received the covenant promise that out of him would come a nation of people, the next person in response to that covenant promise was Isaac, the next one in response was Jacob, and then out of Jacob came the twelve sons, one of whom was Joseph.

While those twelve sons and their families were in Egypt, they exploded in population, and those twelve sons became the twelve tribes of Israel, which Moses led out through the wilderness experience and Joshua led into the land.
