since most of you have become blind, ought there not to be some man to fill this office, and on behalf of all to sing the hymn to God? For what else can I do, a lame old man, than sing hymns to God? If then I was a nightingale, I would do the part of a nightingale: if I were a swan, I would do like a swan. But now I am a rational creature, and I ought to praise God: this is my work; I do it, nor will I desert this post, so long as I am allowed to keep it; and I exhort you to join in this same song.
