Reply To: Kasha on Vayechi

My dad saw an answer in R’ Zvi Hirsch Ferbers sefer. He says that if one makes a shevuah or a neder to someone who is ill its not chal b/c the only reason he makes it is to appease the person. So yaakov didn’t want Yoisef to know that he was a choileh otherwise the neder which he asked him to make wouldn’t be chal. So then it says ‘Vayehi achar hadevarim ha’ele’ after the neder which he made then he was told that yaakov was ill.

(Its still a bit of a kasha as rashi says that Efraim learnt with yaakov and WHEN HE BECAME ILL he sent him to call Yoisef which is mashma that he wasn’t ill before)
