Mark 5:39
And when he was come in, he saith unto them, Why make ye this ado, and weep? the damsel is not dead, but sleepeth.

In John 11:11-13, Jesus uses the identical 'fallen asleep' metaphor for Lazarus, reinforcing death as temporary sleep he can reverse.
In 1 Thessalonians 4:13, Paul calls deceased believers 'asleep' and gives hope of resurrection, echoing Jesus' view that death is temporary.
In 1 Thessalonians 4:14, Paul again uses 'fallen asleep' for dead believers and ties resurrection to Jesus' own, reinforcing the sleep-resurrection link.
In 2 Kings 4:31, Gehazi says the child 'has not awakened', using same sleep imagery for death, and Elisha raises him, prefiguring Jesus' miracle.
In Luke 8:52, the parallel account records Jesus saying the same words to the mourners — 'Do not weep, she is not dead but sleeping.'
In John 11:4, Jesus says Lazarus's illness is for God's glory — similar to declaring the child's death a sleep for God's purpose.
