John 11:9-15

Jesus answered, Are there not twelve hours in the day? If a 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 the light is not in him. These things spake he: and after this he saith unto them, Our friend Lazarus is fallen asleep; but I go, that I may awake him out of sleep. The disciples therefore said unto him, Lord, if he is fallen asleep, he will recover. Now Jesus had spoken of his death: but they thought that he spake of taking rest in sleep. Then Jesus therefore said unto them plainly, Lazarus is dead. And I am glad for your sakes that I was not there, to the intent ye may believe; nevertheless let us go unto him.
