Tobit 2:10
I did not know that there were sparrows on the wall; their fresh droppings fell into my eyes and produced white films. I went to physicians to be healed, but the more they treated me with ointments the more my vision was obscured by the white films, until I became completely blind. For four years I remained unable to see. All my kindred were sorry for me, and Ahikar took care of me for two years before he went to Elymais.
