Take the Challenge
Let him grant me the Cave of Machpelah, which belongs to him, which is at the end of his field; for full money let him grant it to me in your midst for burial property." (Bereishis 23:9)
For the full money — I will pay its full value. And likewise, David said to Aravnah, “for full money.” (I Divrei Hayamim 21: 24).
What does Rashi’s commentary add over and above the simple meaning of the verse? What proof is derived from the verse regarding David, which seemingly does not offer any additional explanation, but uses the same terminology as our verse?
A possible interpretation of “full money” is that the money itself is full, i.e., the coins would contain their full weight. Rashi seeks to negate this interpretation and therefore says “all of its worth,” meaning, Avraham would pay for the entire field. Rashi is compelled to offer this explanation because Avraham’s words are in response to the words of the sons of Ches who offered to give the field for free. If the meaning of “full money” is that the weight of the money is full, then Avrahm’s response is not related to the words of the sons of Ches.
Rashi proceeds to offer a proof to his interpretation from David, who also refused to accept the threshing floor of Aravnah for free, and paid for it instead.
The Wine of Torah:
Both Avraham and David wanted to pay for their purchases, because holiness is achieved through toil and not granted “for free.”
The lesson we learn from here is that even if someone is gifted and he is not challenged by the evil inclination, he must nevertheless invest effort and toil in the service of Hashem.
