raashi commentary on the verse in psalm
"Valley of the shadow of death"
Good nefeshim do not suffer the pangs of death as much as evil nefeshim suffer, for the hazaruth ha mautim touches the prophets only as a shadow. The passage of death comes as a crossing in the death valley that all have to go through, and fear comes only to koferim, not the haredim, ha gadol. That is why it is advised for all, G-d's chosen and goyim alike, to believe in the wager that Pascal partook in.
