Comentario sobre Deuteronómio 7:24

ונתן מלכיהם בידך, "He will deliver their kings into your hand, etc." You will capture them alive. We have proof of this in Joshua 10,26.

ונתן מלכיהם בידך והאבדת את שמם, for allowing any of these Canaanites to survive would become an ongoing source of irritation for you, as demonstrated by the young Haddad, sole survivor of the people of Edom, who became a lifelong source of irritation (militarily) for such a powerful king as Solomon. (Kings I 11,14 and onwards)

ונתן מלכיהם בידך והאבדת את שמם, “He will deliver their kings into your hand and you will cause their reputation to perish.” The few Canaanites remaining in the land during that time will not amount to anything, politically or militarily. Anyone who tries to make a stand against you will fail.

AND HE SHALL DELIVER THEIR KINGS INTO THY HAND, AND THOU SHALT CAUSE THEIR NAME TO PERISH — until they shall have no name abroad⁴⁶Job 18:17. No outside nation will therefore come to their help. — and the Israelites will destroy all who stand up to oppose them. This is similar to what is stated in the Book of Joshua, For it was of the Eternal to harden their hearts, to come against Israel in battle, that they might be utterly destroyed,⁴⁷Joshua 11:20. and not a king was left to them [the Canaanites] in the Land as all their kings fell [in battle].
And Rashi wrote: “Lest the beasts of the field increase upon thee.⁴⁸In Verse 22. But is it not true that when they do His will [as the section begins: And it shall come to pass, because ye hearken to these ordinances etc.] they will have no fear of the beasts, as it is said, and the beasts of the field shall be at peace with thee?⁴⁹Job 5:23. But [this assurance is stated because] it was manifest before Him that they were destined to sin.” These are the words of our Rabbis.⁵⁰Sifre, Eikev 50, with many changes. Now, even though this section is stated as a promise [and any reference to future sin apparently contradicts the principle of man’s freedom of choice], I have already mentioned⁵¹Above, 4:25. that, in the Book of Deuteronomy, Moses our teacher both assures and warns. He alludes to the fact that their merits will not be sufficient to destroy all the people at once and for Him to cause evil beasts to cease out of the Land⁵²Leviticus 26:6. as promised to them in the section If ye walk in My statutes.⁵³Ibid., Verse 3. Instead it will be as he said [here] that they will, in the first stage [of the conquest], destroy most of them together with their kings, and, afterwards, they that are left will be destroyed.
