It's difficult when an area is known by many names. The Holy Land, Palestine, Canaan, Israel, Phoenicia, Judah ... someone would have to spend a lot of time studying religious history and biblical geography to understand it completely. It's a lot like Russia, USSR, Ukraine, Soviet Union, etc. Wars commence, territories vary and boundaries change. Let me share what I've deciphered about the geographical area we call... what is it called?
Canaan was Noah's grandson and the patriarch of the Canaanites. (Noah cursed his grandson Canaan but that's another story). The Canaanites of the north separated themselves from the Canaanites of Israel and became the powerful nation of Phoenicia. They worshiped what Moses called idols, including a sun god they called Baal and a moon goddess they called Ashtoreth or Astarte. They had decadent religious ceremonies that included sacrificing children. What's known as Canaan was Western Palestine, a geographical area surrounded by the Dead Sea, the Mediterranean Sea and the Sea of Galilee. Moses instructed the Israelites to remove all the Canaanites (Phoenicians) from Palestine (Canaan) because they worshiped idols and he feared they would lead the Israelites astray. The Ancient Israelites had a prophecy that Canaan was the land of milk and honey and that God promised it to them for "life everlasting." It's still confusing but it's close enough for the genealogical work I do.
