The g'mara discusses whether oaths that would include other oaths stand
alone or are subsumed. For example, if one says "I will not eat bread"
and then later says "I will not eat bread made of rye", and he then eats
rye bread, has he violated one oath or two? On today's daf
Raba ben Rabbah argues for multiple violations and describes a case
(not involving oaths) where a single action requires five sin/guilt
offerings: a ritually impure person who ate fat that is reserved for
the altar, at a time other than the time of the offering, from an animal
that was set aside for the altar, on Yom Kippur.
R. Meir then raises one: it was Shabbat and he carried the food.
(24b)
Violating (and being punished in accordance with) multiple laws with the
same act is nothing new, we see.
