Commento su Deuteronomio 11:24

EVERY PLACE WHEREON THE SOLE OF YOUR FOOT SHALL TREAD SHALL BE YOURS: FROM THE WILDERNESS etc. In the opinion of our Rabbis³⁵¹Sifre, Eikev 51. they constitute two assurances: [First,] that whatever place in the land of Shinar and the land of Assyria and elsewhere they want to conquer, shall be theirs; and that all the commandments are applicable there, because they all are [part of] the Land of Israel [as Scripture says], from the wilderness and Lebanon etc. even unto the Back Sea shall be your border, meaning that you are obligated to conquer it and to extirpate the peoples from it, just as he said here, and ye shall dispossess nations greater and mightier than yourselves,³⁵²Verse 23. and to uproot the idols and their appurtenance, as he mentioned above.³⁵³Above, 7:25. And [secondly] he assured them that there shall no man be able to stand against you³⁵⁴Verse 25. whether in the land mentioned or in every place whereon the sole of your foot shall tread.
It is from here that there originated a division of opinion among our Rabbis³⁵⁵Gittin 8b. regarding Syria which they called “the conquest of an individual” [and not a national conquest]. The reason is that David conquered it of his own will, not asking [authorization] of the Urim and Thummim³⁵⁶See Vol. II, pp. 482-484. and not consulting the Sanhedrin. For he was obligated to dispossess all the seven nations first, and afterwards if he wished, he could go to another land as G-d promised here.³⁵⁷But David captured Syria while the Jebusite was still entrenched in Jerusalem (Tosafoth Gittin 8a, quoting the Sifre). And because that conquest [of Syria] was not done in accordance with the commandment of the Torah, some of the Rabbis said that it is not considered “a [legal] conquest” [in the sense that it is annexed to the Land], and regarding the commandments [applicable exclusively to the Land], it has the legal status of outside of the Land of Israel. So it is taught in the Sifre.³⁵¹Sifre, Eikev 51. But some Rabbis say in the Talmud³⁵⁵Gittin 8b. that it is termed “a [legal] conquest,” because, although it was not carried out properly, since David went there and conquered it, the Divine assurance it shall be yours was fulfilled and it is [part of] the Land of Israel.
R’eih

אשר תדרך כף רגלכם, to make war against the seven Canaanite tribes,

כל המקום אשר תדרוך כף רגלכם בו לכם הוא, “Every place where the sole of your foot will tread will become yours;” According to our sages (Sifri on our verse) Moses assured the people of two distinctly separate promises here. 1) Any place the Israelites felt they wanted to conquer would not be denied them. Having done so, the commandments of the Torah would apply in any of the lands conquered as the people were under an obligation to conquer the lands as far as the river Euphrates. Secondly, there is another promise,

V. 24. כל המקום. Nach völliger im V. 23 besprochenen Besitznahme von Palästina soll auch jeder außerpalästinensische von Israel eroberte Ort: ׳לכם יהי, den vollen Charakter des jüdischen Landes, קדושת הארץ, erhalten und allen für ארץ ישראל gebotenen Gesetzesbestimmungen unterliegen. ארם צובה und ארם נהרים, zusammen unter dem gewöhnlichen Namen סוריא, wurden von David erobert, bevor das eigentlich verheißene Land völlig in jüdischen Besitz gekommen, — war doch selbst noch Jerusalem in Händen des Jebusi — und erhielt daher סוריא nicht קדושת א׳׳י, wird überhaupt daher nicht als völlig gesetzmäsige nationale Eroberung begriffen und כיבוש יחיד genannt (siehe ספרי und Gittin 8 a).

from the desert in the south,

והלבנון (siehe Kap. 3, 25).

to the river Euphrates in the north,

הים האחרון ist das Mittelmeer, das man in Palästina, mit dem Angesicht nach Osten gekehrt, im Rücken hat.

as far as the Mediterranean Sea in the west.

יהיה גכולכם das ist das eigentliche euch zugesagte Gebiet (siehe Bamidbar 34).
