Tobit 2:9–10

9 On the same night I returned from burying him, and because I was defiled I slept by the wall of the courtyard, and my face was uncovered. 10 I did not know that there were sparrows on the wall and their fresh droppings fell into my open eyes and white films formed on my eyes. I went to physicians, but they did not help me. Ahikar, however, took care of me until he went to Elymais.
