The top Rashi on Menachos 57:2, if I'm reading it correctly, adds some information as an aside, stating that both Rabi Akiva and Rabi Yose Hag'lili derive from "asher takrivu" that a mincha of a kohen (or perhaps he means specifically the inaugural mincha of a kohen) and the inaugural mincha of the kohen gadol may not be made chametz.
Two questions, of which I'm especially bothered by the second:
- How does Rashi know that they learn this halacha from this pasuk?
- Why does Rashi mention this fact here? He should, I'd think, have mentioned it, if anywhere, as a comment on the passage just before, where the tanaim were quoted.
