According to one opinion in the gemara [Zevachim 20] a Kohen need only wash his hands and feet [קידוש ידים ורגלים] once and it can last for EVEN TEN DAYS as long as he has no היסח הדעת in the interim. [According to the second opinion of Rebbe, he needs a new קידוש every morning].
My wise skype chavrusa
asked - The gemara says that one cannot go 3 days without sleeping [and if he takes an oath that he won't sleep for that long he gets מלקות] and sleeping requires a new קידוש ידים ורגלים so how can the gemara say that he can go on for even 10 days??
Any ideas??
