John 11:12 Meaning

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

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.
