This land was the land of the Canaanites, Hittites, Amorites, Perizzites, Hivites and Jebusites.
Here is some background information on the people living in this land:
From Genesis we first learn of these Canaanite people. We were introduced to Noah’s three sons and their descendants which is where the information below comes from. (See Genesis 9:8: The Sons of Noah) (See also Genesis 10: The Table of Nations) There is a story in Genesis regarding Noah and his son Ham and his son Canaan. Noah cursed Canaan because of the actions of Ham. (Read Genesis 9:20-25 NIV)
Noah –> Ham –> Canaan (The land of Canaan belonged to the Canaanites who were the descendants of Noah and his son Ham)
Canaan –> Hittites, Amorites, Hivites, Jebusites (The canaanites included the sons of Canaan himself. No one really knows who the Perizzites were)
Where is this place? As far as I can tell, It is generally where the current country of Israel is now.
