Tafsiran Ulangan 31:5: Chizkuni & Ibn Ezra

וּנְתָנָ֥ם יְהוָ֖ה לִפְנֵיכֶ֑ם וַעֲשִׂיתֶ֣ם לָהֶ֔ם כְּכָל־הַמִּצְוָ֔ה אֲשֶׁ֥ר צִוִּ֖יתִי אֶתְכֶֽם׃

Yang Mahakekal akan menyerahkan mereka kepadamu, dan kamu harus melakukan kepada mereka sesuai dengan segala perintah yang telah kuperintahkan kepadamu.

Chizkuni

אשר צויתי אתכם, “which I have commanded you.” This is a reference to Deut. 20,16, where G-d had commanded the Jewish people not to allow a single soul of the Canaanites to remain alive, (unless they had left that land of their own accord).

Ibn Ezra

and you will deal with them i.e., to destroy their altars.
