Genesis 27:32 Meaning and Commentary

Genesis 27:32

And Isaac his father said unto him, who [art] thou?
&c.] Hearing another voice more like Esau's than what he had heard before surprised him, and therefore in haste puts this question: and he said, I [am] thy son, thy firstborn Esau;
all which was true in a sense; he was his son, and he was Esau, and he was his firstborn by nature, but not by right, for he had sold his birthright.

Genesis 27:32 In-Context

30 And it came to pass after Isaac had ceased blessing his son Jacob, it even came to pass, just when Jacob had gone out from the presence of Isaac his father, that Esau his brother came in from his hunting.
31 And he also had made meats and brought them to his father; and he said to his father, Let my father arise and eat of his son's venison, that thy soul may bless me.
32 And Isaac his father said to him, Who art thou? And he said, I am thy first-born son Esau.
33 And Isaac was amazed with very great amazement, and said, Who then is it that has procured venison for me and brought it to me? and I have eaten of all before thou camest, and I have blessed him, and he shall be blessed.
34 And it came to pass when Esau heard the words of his father Isaac, he cried out with a great and very bitter cry, and said, Bless, I pray thee, me also, father.
