The Jebusites lived in Jerusalem (which David would conquer), the Amorites were widespread across Canaan. These are the peoples Israel would encounter in the Promised Land.
Memory phrase: God knows every people who has ever lived in every land.
Talk about it: The Jebusites lived in Jerusalem before David captured it. Did you know they trace back to Noah's grandson Canaan?
Prayer: God, You know every person who has ever lived in every city. You know me too, completely.
