Quando Isaque já estava velho, e se lhe enfraqueciam os olhos, de maneira que não podia ver, chamou a Esaú, seu filho mais velho, e disse-lhe: Meu filho! Ele lhe respondeu: Eis-me aqui!
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.
