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