John 11:11-16 NIV

[11] After he had said this, he went on to tell them, “Our friend Lazarus has fallen asleep; but I am going there to wake him up.” [12] His disciples replied, “Lord, if he sleeps, he will get better.” [13] Jesus had been speaking of his death, but his disciples thought he meant natural sleep. [14] So then he told them plainly, “Lazarus is dead, [15] and for your sake I am glad I was not there, so that you may believe. But let us go to him.” [16] Then Thomas (also known as Didymus) said to the rest of the disciples, “Let us also go, that we may die with him.”
