Jamieson, Fausset and Brown on Genesis 25:7

Ge 25:7-11. Death of Abraham.

7. these are the days of ... Abraham--His death is here related, though he lived till Jacob and Esau were fifteen years, just one hundred years after coming to Canaan; "the father of the faithful," "the friend of God" [Jas 2:23], died; and even in his death, the promises were fulfilled (compare Ge 15:15). We might have wished some memorials of his deathbed experience; but the Spirit of God has withheld them--nor was it necessary; for (see Mt 7:16) from earth he passed into heaven (Lu 16:22). Though dead he yet liveth (Mt 22:32).
