271 Now when Isaac was old and his eyes had become clouded so that he was not able to see, he sent for Esau, his first son, and said to him, My son: and he said, Here am I. 2 And he said, See now, I am old, and my death may take place at any time: 3 So take your arrows and your bow and go out to the field and get meat for me; 4 And make me food, good to the taste, such as is pleasing to me, and put it before me, so that I may have a meal and give you my blessing before death comes to me. 5 Now Isaac's words to his son were said in Rebekah's hearing. Then Esau went out to get the meat.

(Read Genesis 27:1-5)
The promises of the Messiah, and of the land of Canaan, had come down to Isaac. Isaac being now about 135 years of age, and his sons about 75, and not duly considering the Divine word concerning his two sons, that the elder should serve the younger, resolved to put all the honour and power that were in the promise, upon Esau his eldest son. We are very apt to take measures rather from our own reason than from Divine revelation, and thereby often miss our way.
