Genesis 25:29

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. Isaac was thus also added to his people, his soul entered the realm of the perfected saints in heaven, to be joined with his body in the resurrection of the dead. The notice of Isaac's death is here inserted in order to conclude his history, although, as a matter of fact, he lived about thirteen years longer. "Jacob was born in the sixtieth year of Isaac's life, and was thus one hundred and twenty years old when Isaac died. But when he was presented to Pharaoh in Egypt, he was one hundred and thirty years old. of this time there were seven fruitful and two unfruitful years since Joseph's exaltation in Egypt, and thirteen years between the selling of Joseph and his exaltation, for he was sold when seventeen, and was thirty when he was raised to honor and power. Hence we must take twenty-three years from the one hundred and thirty years of Jacob to determine his age at the time Joseph was sold; which is thus one hundred and seven. Isaac, therefore, shared the grief of Jacob over the loss of his son for thirteen years. " (Lange.)

And Jacob sod pottage, he cooked a dish of lentils; and Esau came from the field, where he had evidently been engaged in his favorite occupation, and he was faint, ravenously hungry after his strenuous exertions.
