How can the verse "do not touch kodesh" be used by Reish Lakish to teach that one cannot eat sacrificial meat in a state of impurity, when that verse is needed to derive the prohibition for an impure person to eat sacrificial meat before the blood is sprinkled? To resolve the difficulty, the Gemara explains how both can be derived from the same verse.

There is a debate between Rabbi Yochanan and Reish Lakish regarding an impure person who eats sacrificial meat before the blood is sprinkled – is it punishable by lashes or not? Abaye and Rava disagree about the scope of the debate.

Rabbi Yochanan and Reish Lakish also disagree about whether one who brings parts of the body of a non-kosher animal onto the altar receives lashes or not. However, after raising a difficulty with this, they explain that all agree it is forbidden, but not punishable by lashes, as it is a negative commandment that is not written explicitly, but derived from a positive commandment. The debate is regarding a different, but similar issue - bringing a non-domesticated animal – is it a violation of a positive commandment, or is it only forbidden ab initio?

Three versions of a question are brought regarding shirayim. If a disqualified person accepted and sprinkled the blood, does it render the animal disqualified from being used for a sacrifice, e.g. can one take more blood from the animal and sprinkle it on the altar? Or, if a cup with the blood was taken out of the Azara, can one get more blood from the animal? Or, if multiple cups were used to get blood from the animal and one was used for the altar, does the blood from the other cups also get poured on the base of the altar (as shirayim)?

How does the Mishna allow for some mistakes to be rectified? Why are there three different cases like this mentioned in the Mishna – what is unique about each case?
