Augustine of Hippo, on Acts 1:26

“And they gave them lots, and the lot fell upon Matthias, and he was numbered with the eleven apostles.”

“He reproved them by saying, "Are there not twelve hours in the day? If any man walks in the day, he does not stumble." Follow me, if you do not wish to stumble: do not give counsel to me, from whom you ought to receive it. To what, then, refer the words "Are there not twelve hours in the day"? So as to point himself out as the day, he chose twelve disciples. If I am the day, he says, and you the hours, is it for the hours to give counsel to the day? The day is followed by the hours, not the hours by the day. If these, then, were the hours, what in such a reckoning was Judas? Was he also among the twelve hours? If he was an hour, he had light; and if he had light, how was the Day betrayed by him to death? But the Lord, in so speaking, foresaw not Judas himself but his successor. For Judas, when he fell, was succeeded by Matthias, and the twelvefold number preserved. It was not, then, without a purpose that the Lord chose twelve disciples, but to indicate that he himself is the spiritual Day. Let the hours then attend upon the Day, let them preach the Day, be made known and illuminated by the Day, and by the preaching of the hours may the world believe in the Day. And so in a summary way it was just this that he said, "Follow me, if you do not wish to stumble."”
