The problem of whether the meal conducted by Jesus (Mt. 26. 17–30: Mk. 14. 12–26; Lk. 22. 7–22; Jn. 13), was a Passover Seder is a matter of long-standing discussion and need not be entered into or documented here.1 What deserves further attention, however, is the light shed on this question by 1 Cor. 10. 16, which was recently considered in the pages of this journal.2 In this discussion the author cites the view of others that the cup of Mt. 26. 27 refers to the cup of blessing accompanying the Grace After Meals, birkhat hamazon, or in terms of the cup-sequence of the Passover Seder, the third cup.3 The author further indicates that the same scholars generally view ‘the cup of blessing’ at 1 Cor. 10. 16, to be the kosshel berakhah, and take this term to be a technical one that refers to the cup of thanksgiving for food, birkhat hamazon, or again, the third cup of the Passover Seder. Cohn-Sherbok argues, however, that Mt. 26. 27 refers to the fourth cup of the Seder, which accompanies the birkhat hashir, the blessing of song, which comes at the end of Hallel (M. Pes. 10. 7; B. Pes. 118 a).4 Finally, in discussing Paul's phrase, to poterion tes eulogias (1 Cor. 10. 16), Cohn-Sherbok argues that it need not refer to any particular cup of the Seder, and might mean generally a cup consecrated by Jesus.5 16, to be the kosshel berakhah, and take this term to be a technical one that refers to the cup of thanksgiving for food, birkhat hamazon, or again, the third cup of the Passover Seder.
