This is how you will know: The adults who left Egypt with Moses had died. The people now entering Canaan with Joshua replaced them. The coming events would show God's presence and his promise to them.
In Canaan, the Israelites would live among neighbors who worshiped false gods. So Israel might feel tempted to worship their gods and goddesses. None of these false gods deserved worship. By contrast, the Lord is the living God, and he was present among the Israelites.
The Canaanites and Amorites were distinct peoples, but their names sometimes indicated all the pre-Israelite peoples of Canaan. The Hittites were related to the earlier Hittite Empire of Asia Minor that controlled much of Canaan. The Jebusites were from the city-state of Jerusalem, which Israel did not conquer fully until David’s time. Little is known about the other three groups.
