Sforno on Deuteronomy 25:19/ספורנו על דברים כ״ה:י״ט
אתִּמְחֶה אֶת זֵכֶר עֲמָלֵק. מִשּׁוֹר עַד שֶׂה, מִגָּמָל וְעַד חֲמוֹר, כְּמוֹ שֶׁצִּוָּה לְשָׁאוּל (שמואל א טו:ג). וְזֶה כְּדֵי לְהִנָּקֵם מֵעֲמָלֵק עַל שֶׁהֵעֵז פָּנָיו בָּאֵל יִתְעַלֶּה, כִּמְקַנְּאִים לִכְבוֹדוֹ.
1תמחה את זכר עמלק, by killing even their livestock, as King Sha-ul was commanded in Samuel I 15,3. This was intended to avenge the unprovoked attack by Amalek against G’d when, by attacking His people, they demeaned His image, besmirched His honour.
