HaLeivi,
Rashi explain “Vayugad” to mean that Pharaoh sent spies along with the Jews to see if they would come back and the spies sent word that they weren’t coming back but were instead escaping. I also don’t understand your pshat, are you saying that Pharaoh sent them out but his servants didn’t know? Why were they telling him that the Jews ran away?
BaalHabooze,
I don’t know what seforim you mean (kabbalah?). But Rashi doesn’t learn that way so we still need a pshat for Rashi (and other Rishonim).
