Tobit, 2

10. I did not see that there were sparrows on the wall of the courtyard and, as my eyes were open, the hot droppings from the sparrows fell into my eyes and formed a white film on my eyes. I went to find doctors to attend to me for medical treatment but the more ointments they smeared on my eyes, the more blind I became because of the film. Finally I became totally blind. I suffered from blindness for four years. All my brothers were burdened because of me. Ahikar kept me for two years before he departed for Elymiade.
