Genesis 27:1

1. Isaac was old One hundred and thirty-seven years . This we ascertain from Jacob’s history, who was not born until Isaac was sixty years old .

Genesis 25:26. Jacob was one hundred and thirty when he went down into Egypt, (Genesis 47:9,) which occurred in the second year of the famine, (Genesis 45:6,) and seven years of plenty had gone before, (Genesis 41:53,) and Joseph was thirty years old when he stood before Pharaoh . Genesis 41:46. Hence Jacob must have been in his ninety-first year when Joseph was born, and this occurred fourteen years after the flight to Haran. Genesis 29:27, compared with Genesis 30:25-26. Jacob must, therefore, have been seventy-seven when he fled from Esau, and Isaac one hundred and thirty-seven.
