פירוש על במדבר 33:52

והורשתם means, AND YE SHALL DRIVE OUT.

You shall oust. For if it was in the sense of inheritance, it should have said וירשתם ["you shall inherit"]. Alternatively if it meant inheritance, the Torah should not have said, “Before you” because the word “before you” is not appropriate for inheritance.

והורשתם את כל יושבי הארץ, "You are to drive out all the inhabitants of the land, etc." Even though the Torah says in Deut. 20, 16 that: "you must not allow a single soul (of these seven nations) to survive," in this instance the Torah does not speak of the seven Canaanite nations but about others who lived amongst them. This is the reason the Torah chose its words carefully, i.e. "all the ones who dwell in the land," that the Israelites were to drive out even those people who lived there who were not members of the seven nations.
