John 11:8-12

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.

These things said he: and after that he saith unto them, Our friend Lazarus sleepeth; but I go, that I may awake him out of sleep.

Then said his disciples, Lord, if he sleep, he shall do well.
