Genesis 27:32 - Exposition

And Isaac his father said unto him, Who art thou ? The language indicates the patriarch's surprise. And he said, I am thy son, thy firstborn Esau. The emphatic tone of Esau's answer may have been dictated by a suspicion, already awakened by Isaac's question, that all was not right (Inglis). Esau's claim to be regarded as Isaac's firstborn, after having bartered away his birthright, is considered by some to be unwarranted (Wordsworth); but it is doubtful if Esau attached the importance to the term "firstborn" which this objection presupposes.
