John 11:9-11

⁹Jesus answered, Are there not twelve hours in the day? If any man walketh in the day, he stumbleth not, because he seeth the light of this world.

¹⁰But if a man walketh in the night, he stumbleth, because there is no light in him.

¹¹These things he said: and after that he saith to them, Our friend Lazarus sleepeth; but I go that I may awake him out of sleep.
