In the previous shiur, we completed our discussion of the sugya that includes the story of Binyamin the Shepherd. We saw how the ambiguity in the peshat of the sugya actually led to two identical halachic rulings in the Shulchan Aruch that the wording Binyamin used works (בדיעבד) in place of both the blessing of HaMotzi and the first blessing (HaZan) of Birkat HaMazon. Then we read, translated, parsed and discussed the following short sugya, which examines the dispute between Rav and R.Yohanan about the minimum requirements for content of a bracha. Please review this material and if there are any questions I will be happy to discuss them at the beginning of this shiur.
In this shiur, we will finish our discussion in depth of the dispute between Rav and R.Yohanan. We will first learn more carefully the baraita that Abaye brings in support of Rav. Then we will study the Tosafot that relates to the halachic conclusions from this piece of gemara. Following this and time allowing, we will learn the new mishna, about the applicability of the blessing she-haKol. All of this is in the middle of the page at Berachot 40b.
