Comentario sobre Génesis 23:17

ויקם שדה עפרון AND THE FIELD OF EPHRON WAS MADE SURE (literally, it rose) — It received a rise in importance because it passed from the possession of a commoner (הדיוט an ordinary person) into the possession of a king (Genesis Rabbah 58:8). But the real meaning of the verse is: The field and the cave that was therein and all the trees … became secured to Abraham as a possession etc. (i. e. verse 17 is an incomplete sentence and must be read together with verse 18, thus: ויקם השדה וגו… לאברהם למקנה —The field etc. became secured to Abraham as a possession).

ויקם השדה לאברהם למקנה, the word ויקם teaches that the purchase was confirmed by a sealed document

ויקם, it “arose” for Avraham as a purchase, and acquisition. The unusual sounding word קם here also occurs in this sense in Leviticus 27,19 וקם לו, where it describes the legal procedure of redeeming property from the Temple treasurer by paying a premium. The term is chosen to describe a transaction of a permanent, enduring nature.
