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.
