Blood from a sin offering is disqualified if brought into the sanctuary. Is the same true for sin offering blood that was meant to be presented in the sanctuary and was brought into the kodesh hakodashim? The sources are brought for the debate between Rabbi Eliezer and Rabbi Shimon about the prohibition being only if the blood was presenting in the sanctuary or even if it was just brought inside. Rabbi Yehuda exempts blood that was accidentally brought into the sanctuary – but would he say that if it was brought intentionally, would it be disqualified only if it was presented or not? The new chapter starts with a debate regarding what disqualified items are sanctified if they are in any case brought on the altar – such that if they were put on the altar, one does not need to remove them. Five different opinions are presented.
