HOW ISAAC DIED, AND WAS BURIED IN HEBRON. FJAJ 1.115

FROM thence Jacob came to Hebron, a city situate among the Canaanites; and there it was that Isaac lived: and so they lived together for a little while; for as to Rebeka, Jacob did not find her alive
Isaac also died not long after the coming of his son; and was buried by his sons, with his wife, in Hebron, where they had a monument belonging to them from their forefathers
Now Isaac was a man who was beloved of God, and was vouchsafed great instances of providence by God, after Abraham his father, and lived to be exceeding old; for when he had lived virtuously one hundred and eighty-five years, he then died. FJAJ 1.116
