When Isaac was old A hundred and thirty-seven years old; but he lived forty years after this. And his eyes were dim Whereby God brought about his own purpose of bestowing the blessing on Jacob. He called Esau, his eldest son With a view to declare him his heir. The promise of the Messiah, and the land of Canaan, was a great trust, first committed to Abraham, inclusive and typical of spiritual and eternal blessings; this, by divine direction, he transmitted to Isaac. Isaac, either not knowing, or not duly considering the divine oracle concerning his two sons, that the elder should serve the younger, resolves to entail all the honour and power that was wrapped up in the promise upon Esau his eldest son. Esau had greatly grieved his parents by his marriage, yet they had not expelled him, but it seems were pretty well reconciled to him.
