Noah fathered Shem, Ham and Japheth and that is where our next story begins with the life of Noah.
The reason that God includes these generations of families in the Bible is because of the promises made in the previous chapters to these families and their descendants. This list is not just records of generations but also evidence of God’s faithfulness to the promises made generations ago.
