Rashi
but the desire of the treacherous is violence Heb. ונפש. The desire of the treacherous is violence, as in (Gen. 23:8): “If it is your desire (נפשכם)” and (Ps. 27:12): “Do not give me for the desire of (בנפש) my adversaries.”
Ibn Ezra
שְׁאׇלוּגׅי Ask me. It is imperative like שְׁמׇלוּגׅי hear me (Gen. 23:8), the kamez being substituted for zeré because of the guttural letter (א) 14The regular form would be שַׁאֲלוּגׅי שׁׅמׅעוּגׅי. See I. E. on 41:25, and Note 31..
Or HaChaim
והמערה אשר בו, "as well as the cave situated on it." He meant that already at the very beginning of the discussions when the local people had indicated their willingness to relinquish their own burial plots in favour of Abraham, he, Efron had decided that the cave and the field were a single unit. The reason he repeated the fact that the transaction took place in full view of all the people was to make plain that no דין מצר could be invoked by anyone in the future.
Rashi
my desire Heb. נפשי. This [word denoting] a person’s temptation toward desire [is used] in many places, as (Gen. 23:8), “If it is truly your will (נפשכם).”
