John 11:11-14
11These 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. 12Then said his disciples, Lord, if he sleep, he shall do well. 13Howbeit Jesus spake of his death: but they thought that he had spoken of taking of rest in sleep. 14Then said Jesus unto them plainly, Lazarus is dead.
