John 11:11-15

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. Howbeit Jesus spake of his death: but they thought that he had spoken of taking of rest in sleep. Then said Jesus 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.
