John 11:7-10

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.
