Genesis 35:28-294. Isaac’ s Death (Genesis 35:28-29) Isaac died at the age of one hundred and eighty years. His death was as uneventful as his life. He did not die, however, as soon as he thought he would (Genesis 27:1-2), but lived forty years longer, at least until Joseph was about thirty years old. The story of Isaac’ s life closes with the words: “ And the days of Isaac were an hundred and fourscore years. And Isaac gave up the ghost, and died, and was gathered unto his people, being old and full of days: and his sons Esau and Jacob buried Him” (Genesis 35:28-29).
