EXTRA · Side-ring · Parashas Shoftim · Passuk 20:15
Thus you shall do to all the cities that are very far from you, which are not of the cities of these nations.
Chazal / classical source (beyond TT-numbered main-ring units): Sifrei Devarim 200 / Rambam.
Lemma: אֲשֶׁר לֹא מֵעָרֵי הַגּוֹיִם הָאֵלֶּה הֵנָּה.
Sefaria — Sifrei Devarim 200 / Rambam
English: ‘Which are not of the cities of these nations’ – to exclude the seven peoples.
Derash excluding the Canaanite nations (Sifrei) — the herem of the Land is a separate category.
The Torah carefully distinguishes the distant cities (to which these rules apply) from the cities of the seven nations, which fall under the law of complete herem.
