More comparisons between chametz and hekdesh - including the phenomenon of the prohibition of food, and including chametz that is hekdesh on Pesach. Plus: Another example of two prohibitions coming together - in the case of having to pay damage from an action that itself violated Shabbat or Yom Kippur. Also - mixtures of prohibited food together with permitted food. Verging into the concepts that are most relevant in Hilkhot Kashrut... For example, what it takes for a food to be nullified in a larger amount of food... and when chametz can't be nullified at all.
