Génesis 23:11 Comentario: Rashi, Chizkuni, Ramban & Or HaChaim

לא אדני NAY, MY LORD — You are not to buy it with money.

השדה נתתי לך, “I have given you the field;” Efron pointed out that unless he gave Avraham not only the cave of Machpelah but also his adjoining field, Avraham would have no access to the cave. (without asking permission to visit there each time).

IN THE PRESENCE OF THE SONS OF MY PEOPLE. The intent thereof is to state: “Behold, all the people are present, and they are knowledgeable witnesses to the sale. Therefore do not fear denial or retraction, and so bury thy dead from now on, for it is yours and I cannot retract.” But Abraham did not do so for even after he paid its full value in silver he first took symbolic legal possession of the field and the cave. He established them as his possession in the presence of the people of the city, and all those who came in at the gate of the city,³³Verse 18 here. the merchants and the residents who happened to be there, and after that he buried her.

נתתי לך I HAVE GIVEN IT TO THEE (a perfect tense) — See, it is as though I have already given it to you.
