תלמוד על ברכות 17:20

Rebbi Jeremiah asked, what did you see to say that evening is later³¹Since starting at 12:01 pm one greets with “good evening”.; could we not say that between the evenings is later? But it must be: The one about which is written between the evenings at sundown³¹Since starting at 12:01 pm one greets with “good evening”. shall be delayed more than one about which is written only between the evenings. The formulation of a baraita³²Babli Berakhot 9a, Sifry Deut. 113 in the name of R. Eliezer; different wording and authors Mekhilta dR. Ismael Bo 5, last sentence. supports Rebbi Jeremiah: “There you shall slaughter the Pesaḥ in the evening. In the evening you are slaughtering, at sundown you are eating, at the time of your exodus from Egypt you are roasting³³Since obviously roasting must precede eating and the day of the Exodus was the 15th of Nisan, the day after the night dedicated to the Pesaḥ, with the parallel sources one has to understand “roasting” as “burning” the remainders (Ex. 12:10)..” There are Tannaim who state: “In the evening you are eating, at sundown you are slaughtering, at the time of your exodus from Egypt you are roasting.”
