Tafsiran Ulangan 7:13: Rashi, Alshekh, Ramban & Ibn Ezra

שגר אלפיך means the offspring of thy oxen which the female casts out (שגר) from its womb.

On the land. Even though in general these things do not depend on merit but on luck, there is no such thing as luck in the land of Israel.

VA’AHEIVCHA’ (AND HE WILL LOVE THEE). The meaning thereof is that when you will observe the ordinances [i.e., the judgments] out of a love for G-d, He will love you as well. It is possible that va’aheivcha is transitive, meaning that He will cause you to be beloved by the families of those judged [to punishment] and you will not be hated because of [what you have done to] them. And He will bless thee,³¹In Verse 13 before us. that there shall no evil befall thee³²Psalms 91:10. because of the judgment [you have rendered]. And He will multiply thee,³¹In Verse 13 before us. that you will not be diminished because of the death of the transgressors, even if many are slain such as the people of an apostate city.³³Further, 13:13-19.

ועשתרות צאנך AND THE BREEDS OF THY FLOCK — Menachem ben Seruk explains this expression to be parallel to אבירי בשן, which means: "the strong rams of Bashan” (Psalms 22:13), i.e. the choicest of the sheep, similar to (Genesis 14:5), “Ashteroth (עשתרות) Karnaim", where also it is an expression for “strength" (so that עשתרות denotes “the strong ones"). Onkelos. however, translates it: “and the flocks of thy sheep". Our Rabbis said: Why is their name called עשתרות? Because they enrich (עשר) their owner (through the sale of their wool, etc.) (cf. Chullin 84b).
