Mishnah Challah
Ben Antigonus brought up firstlings from Babylon, but they did not accept from him. Joseph the priest brought first fruits of wine and oil, but they did not accept from him. He also brought up his sons and members of his household to celebrate Pesah katan in Jerusalem, but they turned him back, so that the thing should not become firmly fixed as an obligation. Ariston brought his first fruits from Apamea and they accepted from him, because they said, one who buys [a field] in Syria is as one who buys [a field] in the outskirts of Jerusalem.
Mishnah Pesachim
Five things [sacrifices] may come in uncleanness, but may not be eaten in uncleanness:the omer, the two loaves, the showbread, the sacrifices of the public peace-offerings, and the goats of new months. The pesah which comes in uncleanness is [also] eaten in uncleanness, for from the very beginning it came for no other purpose but to be eaten.
Mishnah Pesachim
He who was unclean or on a far-off journey and did not keep the first [Pesah] must keep the second. If he unwittingly erred or was prevented and did not keep the first, he must keep the second. If so, why does it say “an unclean person” and “one who was one a long journey” specified? That these are not liable to karet, whereas these are liable to karet.
