Augustine of Hippo
Catena Aurea · Johannesevangelium 11
When he had heard therefore that he was sick, he abode two days still in the same place where he was. Then after that saith he to his disciples, Let us go into Judæa again. His disciples say unto him, Master, the Jews of late sought to stone thee; and goest thou thither again? Jesus answered, Are there not twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world. But if a man walk in the night, he stumbleth, because there is no light in him. Then after that saith He to His disciples, Let us go into Judæa again.
(Tr. xlix. 8) When men presumed to give advice to God, disciples to their Master, our Lord rebuked them: Jesus answered, Are there not twelve hours in the day? He shewed Himself to be the day, by appointing twelve disciples: i. e. reckoning Matthias in the place of Judas, and passing over the latter altogether. The hours are lightened by the day; that by the preaching of the hours, the world may believe on the day. Follow Me then, saith our Lord, if ye wish not to stumble: If any man walk in the day, he stumbleth not, because he seeth the light of this world: But if a man walk in the night he stumbleth, because there is no light in him.
