ספר בראשית

Still on the subject of the tone sign shalshelet over the ‎word ‎וימאן‎, according to G’d’s plan, Joseph was meant to interpret ‎the dreams of the Royal cupbearer and the chief of the Royal ‎bakers. The dream of the latter involved three baskets, whereas ‎the dream of the former involved three grape bearing branches ‎on a vine. According to the Talmud in Chulin 92, the ‎dreams of these servants of Pharaoh are alluded to in the tone-‎sign that directs our attention to the number 3, as are the three ‎names by which Joseph is called at various times in the Bible, i.e. ‎יוסף‎, ‎יהוסף‎ and ‎צפנת פענח‎ which Onkelos translates as ‎גברא דמטמרן‎ ‎‎“a man who could reveal that which was hidden.” The ‎שלשלת‎ ‎would refer to three dreams that Joseph had to interpret after ‎this event.‎
