For I will drive out the nations before you and enlarge your borders. No man will covet your land when you go up to appear before the Lord your God three times in the year.
The Lord your God will drive out those nations before you, little by little. You will not be able to destroy them all at once, lest the beasts of the field become too numerous for you.
The people of Judah were not able to drive out the Jebusites living in Jerusalem, so the Jebusites live with the people of Judah in Jerusalem to this day.
They did not drive out the Canaanites who lived in Gezer, so the Canaanites live in the midst of Ephraim until this day performing heavy labor as slaves.
