“Abraham hurried to the tent, to Sarah, and said: Quickly prepare three se’a of high quality flour, knead and make cakes” (Genesis 18:6). “Abraham hurried to the tent, to Sarah, and said: Quickly [prepare three se’a of high quality flour, knead and make cakes]” – Rabbi Evyatar said: She baked nine se’a – three for cakes, three for dumplings, and three for various pastries. The Rabbis said: There were three [se’a altogether] – one for cakes, one for dumplings, and one for pastries.
“Knead and make cakes [ugot]” – that teaches that it was the onset of Passover.30As it is written: “They baked the dough that they had taken out of Egypt into unleavened cakes [ugot]” (Exodus 12:39). Rabbi Yona in the name of Rabbi Ḥama bar Ḥanina: The wilderness of Sin31Where the manna began to fall for the Israelites (Exodus chapter 16). and the wilderness of Alush32Mentioned as one of the stations of the Israelites in the wilderness (Numbers 33:13). are one and the same.
By what merit were the people of Israel privileged to eat manna in the wilderness? It was by the merit of Abraham, who said: “Knead [lushi] and make cakes.”
