Shevuos 2:1-2

Shevuos 2:1

There are two laws regarding awareness of ritual impurity that are four: if a person was rendered ritually unclean and was aware of it, then he forgot about his own impurity but he remembered that the food was sanctified; if he was unaware that the food was sanctified but remembered about his impurity; if he forgot about both, ate sanctified food in his state of unawareness, and subsequently became aware – in these cases, he must bring a korban oleh v’yoreid (variable guilt offering). If he was rendered ritually unclean and was aware of it, then he forgot about his own impurity but he remembered that the place was the Temple; if he was unaware that it was the Temple but he remembered that he was unclean; if he was unaware of both and entered the Temple in his state of unawareness and only became aware after he had exited – in these cases he must bring a korban oleh v’yoreid.

Shevuos 2:2

It makes no difference whether a person enters the Temple courtyard or the section later added to the Temple courtyard (i.e., one is equally liable in either case) since additions could only be made to Jerusalem and the Temple courtyard by a joint act of the king, a prophet, the urim v’tumim and the Great Sanhedrin of 71 judges, with two thanksgiving offerings (loaves) and song. The members of the court would walk in a procession, followed by the two thanksgiving offerings, and finally all the people. The loaf that was carried on the inside was eaten and the one that was carried on the outside was burned. If an addition was made to the Temple courtyard without following this procedure, then one would not be not liable for entering it in a state of ritual impurity.
