Why does the Torah break off the narrative here, to discuss the lineage of Reuven, Shimon and Levi?
Rashi #1, Rashbam #1 and Seforno: It is important at this juncture to present the Yichus of Levi on account of Moshe and Aharon. 1 And it would not have been befitting to begin with Levi, 2 so it begins with Reuven.
Rashi #2 (citing the Pesikta Gedolah) and Rashbam #2 (citing the Mechilta): The Torah makes a point of presenting the lineage of Reuven Shimon and Levi, to demonstrate their importance, since Ya'akov berated them before his death.
What is the meaning of "Tufinei"?
Rashi: It means baked many times; 1 after scalding it in boiling water, the Kohen bakes it in the oven once more and fries it in a pan.
Rashbam: It is an expression of baking. 2
Targum Yonasan: It means fried.
What are the implications of "Minchas Pitim"?
Rashi, Targum Onkelos and Targum Yonasan: It teaches us that the Minchas Chavitin must be broken into pieces. 1
Not broken literally, but folded into two and then into four. It does not require true breaking, since it is not subject to Kemitzah (Rashi Yashan).
