John 11:11-15

These things He said, and after that He said to them, “Our friend Lazarus sleeps, but I go that I may wake him up.” Then His disciples said, “Lord, if he sleeps he will get well.” However, Jesus spoke of his death, but they thought that He was speaking about taking rest in sleep. Then Jesus said to them plainly, “Lazarus is dead. And I am glad for your sakes that I was not there, that you may believe. Nevertheless let us go to him.”
