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.
Ge 27:1-27. Infirmity of Isaac.
1. when Isaac was old, and his eyes were dim—He was in his hundred thirty-seventh year; and apprehending death to be near, Isaac prepared to make his last will—an act of the gravest importance, especially as it included the conveyance through a prophetic spirit of the patriarchal blessing.
