“And it came to pass, that when Isaac was old, and his eyes were dim, so that he could not see, he called Esau his eldest son, and said unto him, My son: and he said unto him, Behold, here am I.”
King James Version (KJV)
27:1 Here is Isaac's design to declare Esau 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 being now old, and 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 wrapt up in the promise upon Esau, his eldest son. He called Esau - Tho' Esau, had greatly grieved his parents by his marriage, yet they had not expelled him, but it seems were pretty well reconciled to him.
