The next burial in the cave is that of Abraham himself, who at the age of 175 years was buried by his sons Isaac and Ishmael. The title deed to the cave was part of the property of Abraham that passed to his son Isaac. The third burial was that of Isaac, by his two sons Esau and Jacob, who died when he was 180 years old. There is no mention of how or when Isaac's wife Rebecca died, but she is included in the list of those that had been buried in Machpelah in Jacob's final words to the children of Israel. Jacob himself died at the age of 147 years.
