Musar על בראשית 35:2

הסירו את אלהי הנכר . Man must make an effort to return to G–d wholeheartedly at all times, and to remove from his home all alien and forbidden objects, foods, etc. Anything that is displeasing in the eyes of G–d is called Avodah Zarah, a form of alien deity. We must keep our homes pure so as to conform with the Torah's command to the Jewish soldier: והיה מחניך קדוש, "ensure that your camp is holy" (Deut. 23, 15).
