13. Now that the vintage vacation was ended, I gave notice to the citizens of Milan that they might provide their scholars with another word-merchant. I gave as my reasons my determination to serve thee and also my insufficiency for the task, because of the difficulty in breathing and the pain in my chest.
And by letters I notified thy bishop, the holy man Ambrose, of my former errors and my present resolution. And I asked his advice as to which of thy books it was best for me to read so that I might be the more ready and fit for the reception of so great a grace. He recommended Isaiah the prophet; and I believe it was because Isaiah foreshows more clearly than others the gospel, and the calling of the Gentiles. But because I could not understand the first part and because I imagined the rest to be like it, I laid it aside with the intention of taking it up again later, when better practiced in our Lord’s words.
