Genesis 10 is the "Table of Nations." It outlines the descendants of the three sons of Noah.
While there isn't much narrative in this text (though there is some!), what you should notice is that all of Genesis 10 is a fulfillment of God's 3x blessing to Noah:
Bring out with you every living thing of all flesh that is with you, birds and animals and every crawling thing that crawls on the earth, that they may breed abundantly on the earth, and be fruitful and multiply on the earth.”
Genesis 8:17 (NASB)Then God blessed Noah and his sons, and said to them, “Be fruitful and multiply, and fill the earth.
Genesis 9:1 (NASB)As for you, be fruitful and multiply; Populate the earth abundantly and multiply in it.
Genesis 9:7 (NASB)
