וַיֹּ֤אמֶר יַעֲקֹב֙ אֶל־בֵּית֔וֹ וְאֶ֖ל כָּל־אֲשֶׁ֣ר עִמּ֑וֹ הָסִ֜רוּ אֶת־אֱלֹהֵ֤י הַנֵּכָר֙ אֲשֶׁ֣ר בְּתֹכְכֶ֔ם וְהִֽטַּהֲר֔וּ וְהַחֲלִ֖יפוּ שִׂמְלֹתֵיכֶֽם׃
Jacob dit à sa famille et à tous ses gens: "Faites disparaître les dieux étrangers qui sont au milieu de vous; purifiez vous et changez de vêtements.
Rashi on Genesis
הנכר [PUT AWAY] THE STRANGE [GODS] —which you have in your possession from the spoil of Shechem.
Rashbam on Genesis
אלוהי הנכר, which they had looted from Shechem.
Sforno on Genesis
הסירו את אלוהי הנכר, which you have taken from Shechem. Even though the adherents of these idols had already disowned them, (the surviving females of the city of Shechem), and we know from Avodah Zarah 43, and 52 that such items are subsequently permitted to Jews, Yaakov commanded his household to get rid of them before proceeding to Bet El. He wanted all his people to mentally completely dissociate themselves from anything connected wit items formerly used in idolatrous pursuits.
