Comentario citado sobre Génesis 14:24

for...young men They are the ones who go with him to rob, as in (Gen. 14:24), “only what the young men have eaten.”

[Divide the spoils] with your brothers— Referring to Bnei Gad and Bnei Reuvein. There are some who interpret “brothers” in referrence to those who remained behind to guard the cities and the women and children. [Even though] they did not cross the Jordan— with the armed division, nevertheless they received a share of the spoils.¹This practice was instituted by Avrohom. See Bereishis 14:24. Rashi comments there that Dovid learned from Avrohom’s action and established this as a tradition.

וירק את חניכיו, “he mobilised all those whom he had trained;” Avraham told all these men that they were about to go to war and if someone was afraid for his life due to sins he had committed, he was free to go back home. (Compare Deuteronomy 20,8) When they heard this, they all decided to return to their homes, with the exception of his loyal servant Eliezer. G–d told Avraham not to worry and to let them go home, as He would empower Eliezer to possesss as much power as all these men had possessed combined. The numerical value of the letters in the name אליעזר total 318, and that is why the Torah described his ”army” as consisting of 318 men. (Compare Talmud, tractate Nedarim, folio 31) In addition, we have two interpretations of the Talmud scholars Rav and Sh’muel, respectively, the former saying that the word וירק in our verse refers to “pouring words of Torah into these potential soldiers, whereas Sh’muel says that he overcame their fears by giving them large quantities of gold. (same folio in the Talmud) His objective was to instill in these men the will to save as many lives as possible, not to fight for the sake of the loot they might capture by killing fellow human beings. [This editor has some difficulty with the explanations offered, as in verse 24 of our chapter Avraham insists that the men who had fought with him receive their share of the loot. Ed.]

From that day on. [Literally 'from that day and above']. It is not stated: "[from that day] on" but "[from that day] and above [=before]." Avrohom had already instituted this statute [when he said,] "Only what the lads have eaten,"⁵Bereishis 14:24, where it is stated that Avrohom distributed shares of the spoils of war to those who stayed behind and guarded the equipment. those are the ones who stayed with the equipment, "and the portion of the men"⁶Ibid. who went to war. In Breishis Raboh.
