I have given you the land. "The earth is the Lord's," and no one, therefore, can dispute his right in the abstract to evict any of his tenants and to put others in possession. But while the whole earth was the Lord's, it is clear that he assumed a special relation towards the land of Canaan, as to which he chose to exercise directly the rights and duties of landlord (see on Deuteronomy 22:8 for a small but striking instance).
The first duty of a landlord is to see that the occupancy of his property is not abused for illegal or immoral ends; and this duty excuses, because it necessitates, eviction under certain circumstances.
It is not, therefore, necessary to argue that the Canaanites were more infamous than many others; it is enough to remember that God had assumed towards the land which they occupied (apparently by conquest) a relation which did not allow him to overlook their enormities, as he might those of other nations (see on Exodus 23:23-33; Exodus 34:11-17, and cf.
Acts 14:16; Acts 17:30). It was (if we like to put it so) the misfortune of the Canaanites that they alone of "all nations" could not be suffered to "walk in their own ways," because they had settled in a land which the Lord had chosen to administer directly as his own earthly kingdom.
