1 Samuel 30:11

And they found an Egyptian in the field, and brought him to David, and gave him bread, and he did eat; and they made him drink water;

David with his four hundred men was pursuing the Amalekites who had attacked and burned Ziklag when an exhausted Egyptian was found in the field. He was given bread and water to eat and drink, together with a piece of fig cake and two clusters of raisins, and after he ate his spirit came to him again.

That coming again of his spirit was the return of strength and life and breath after faintness from hunger and thirst when he ate and drank. It was not the return of a separate conscious soul or entity after death. Since he had not died and had not lost his reason, the phrase does not prove that man has two conscious entities within him or that the spirit lives consciously apart from the body. The popular idea of the spirit as an independent immortal entity is unscriptural.
