The Bible records a number of people who died and was restored to life.
Elijah brought the widow of Zaraphath's son back to life in 1 Kings 17:17-24.
When the son of a Shunnamite woman died, Elisha raised him from the dead in 2 Kings 4:25-27.
A dead man who was thrown into Elisha's grave was restored to life when his body came into contact with the bones of Elisha in 2 Kings 13:20-21.
Each of these people actually died and was restored to life, but they were not resurrected, not in the biblical sense.
In the Bible, the resurrection of God's people [Christians] refers not merely to the restoration of life, but it speaks of the transformation and glorification of the body.
Resurrection indicates immortality.
Those who were raised from the dead, eventually died again, but those who are resurrected will never die again.
