Genesis 9-10  The Lord "blessed Noah and his sons.. "  A new society was begun with this small family.  A new covenant was given :

All animals were given for food now,  as well as the plants;
They were never to eat something still alive, with its blood.
They would be held responsible for bloodshed - blood for blood;
They were to be fruitful and multiply and fill the earth;

As a sign of this covenant God set His "bow" in the cloud.  It is an" everlasting covenant between God and every living creature of all flesh that is on the earth."  ( v16)

But, sin reared it's ugly head quickly enough in this new world.
Noah planted a vineyard, made some wine, and passed out drunk.
His son Ham "saw the nakedness of his father" and went to tell his brothers.
Shem and Japheth carefully covered their father with their faces turned away.
Because of this, Ham's lineage was cursed, starting with his son Canaan.

Chapter 10 gives the genealogy of Noah's sons.
Out of Ham's descendants we learn the origins of the Assyrians, The city of Babel; The Philistines;  The Canaanites, the Amorites and the Jebusites. All these will become enemies of God's chosen people.

On the other hand, the descendants of Shem will lead to Abraham.

All three of Noah's sons would establish cities and become nations.  They all had the same covenant and same opportunity, but choices were made.  Same for us.. we all have the same opportunity to put our faith in the Lord Jesus Christ who died for our sins.  We have the choice to deny ourselves, take up our crosses, and follow Him... or we can harden our hearts and go our own way.. the way of destruction.

Father in heaven, You are the God of mercy and grace and we hallow Your Name.  Thank You for the gift of salvation through Jesus Christ, Your Son.  May we not harden our hearts but open them wide to receive Your Word and to live in covenant relationship with You forever. Amen.
