Now it came about, when Isaac was old and his eyes were too dim to see, that he called his older son Esau and said to him, 'My son.' And he said to him, 'Here I am.'
(New American Standard Bible)
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)
