Dedicated to the proposition that performing two labors in one state of unawareness on Shabbat makes a person liable for only one sin offering.
Or – based on the example of one who accidently eats of forbidden sacrificial meat (heleb), maybe not. If one is informed and then eats a second piece, but didn’t understand that the second was also proscribed – one sacrifice is sufficient for the two. But NOT if a third piece is taken.
There are limits!
