John 11:11-15

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.
