Pesahim 23a and Pesahim 23b, a series of topic areas where the Torah uses the verb of akhilah, so R. Avahu should think there’s a prohibition of benefit, and yet finds an extra verse to teach there is not. Then, whether R. Yose HaGlili and R. Akiva had this debate as well, and finally, seeking a difference in practice between R. Avahu and Hizkiyah (who did not think akhilah implied a prohibition of benefit).
