Origen, on Josh 15:63

“But the children of Juda could not destroy the Jebusite that dwelt in Jerusalem: and the Jebusite dwelt with the children of Juda in Jerusalem until this present day.”

“Concerning Jerusalem, we have frequently said that it means "a vision of peace." If, therefore, Jerusalem has been built in our heart—that is, if the vision of peace has been established in our heart and we always contemplate and retain in our heart Christ, who is "our peace"—if indeed we are so fixed and firm in this vision of peace that absolutely no evil thought or consideration of some sin ever rises up into our heart, if this could be so done, we would be able to say that we are in Jerusalem and no one else dwells with us except those who are holy. But now, even though we make great progress and improve ourselves with the utmost zeal, nevertheless I do not think anyone turns out to be so pure of heart that he is never defiled by the contamination of a contrary thought. Therefore, it is still certain that Jebusites dwell with the sons of Judah in Jerusalem. Yet we do not say these things so that we may neglect to cast them out as far as it may be done. On the contrary, we must be amply concerned and must attempt daily to cast them from Jerusalem; but, just as it is written, we cannot cast all out at the same time.”
