John 11:12 in the King James Version
Then said his disciples, Lord, if he sleep, he shall do well.
Context
11 He said these things, and after that, he said to them, “Our friend Lazarus has fallen asleep, but I am going so that I may awake him out of sleep.”
12 The disciples therefore said, “Lord, if he has fallen asleep, he will recover.”
13 Now Jesus had spoken of his death, but they thought that he spoke of taking rest in sleep.
