Kommentar zu Bereschit 23:8

נפשכם means YOUR WILL.

IF IT BE YOUR MIND TO BURY MY DEAD FROM BEFORE ME. The intent thereof is: “I will not bury my dead in another burial ground. However if it be your desire that I bury my dead, entreat for me to Ephron who has a cave at the end of his field, which is not used as his family burial-place but as a field.” The meaning of the word milphanai, (from before me), is that if you will not do so I will entomb her in a casket. It may be that it means “my dead wife who is before me, and as an obligation I must hurry to bury her.” The reason Abraham requested, and entreat for me, is that Ephron was a rich and distinguished person, as is indicated by his saying, What is that between me and thee?²⁸Verse 15: Land worth four hundred shekels of silver — what is that between me and thee? It would therefore not be to his honor to sell his ancestral inheritance, as was the case with Naboth of Jezreel.²⁹I Kings, Chapter 28. It was for this reason that Abraham did not go to Ephron to offer him an inflated price for the field, but instead he asked of the people of the city to entreat to him [Ephron] on his behalf in an honorable way.

אם יש את נפשכם לקבור, if you want that I shall bury the dead without delay, as you have indicated when you said: במבחר קברנו קבור!" (verse 6) i.e. that I would not need to wait.
