1. Mose 27:1

Und es begab sich, da Isaak alt war geworden und seine Augen dunkel wurden zu sehen, rief er Esau, seinen älteren Sohn, und sprach zu ihm: Mein Sohn! Er aber antwortete ihm: Hier bin ich.

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.
