John 11:4

11:4 When Jesus heard this, he said, “This sickness will not lead to death, but to God’s glory, so that the Son of God may be glorified through it.”

John 11:11-13

11:11 After he said this, he added, “Our friend Lazarus has fallen asleep. But I am going there to awaken him.” 11:12 Then the disciples replied, “Lord, if he has fallen asleep, he will recover.” 11:13 (Now Jesus had been talking about his death, but they thought he had been talking about real sleep.)
