Komentaryo sa Genesis 23:9: Rashi, Chizkuni, Ramban & Rashbam

המכפלה MACHPELAH (the root, כפל, means double) — it had a lower and an upper cavern. Another explanation of why it was so called is, because it has the characteristic of being doubled on account of the couples who are buried there (see Rashi in verse 2) (Eruvin 53a).

ויתן לי, “so that he will give me, etc.” Avraham never suggested that he wanted the cave of Machpelah as a gift; on the contrary, he considered that even after having paid a substantial amount of money for it, he would still view this as a gift bestowed upon him by Efron.

THAT HE MAY GIVE ME. The intent of this is “that he may give it to me in such a way that I will consider it as a gift (even) if I will buy it from him for its full value.” It is for this reason that Abraham did not mention the word “selling.” A similar usage is found in the verse, Thou shalt sell me food for money, that I may eat; and give me water for money, that I may drink,³⁰Deuteronomy 2:28. meaning “for the water which is usually given as a gift I will give money.” It may be that such is the ordinary usage of the language to mention “giving” when describing sales transactions.
