וַיְדַבֵּ֥ר יְהוָ֖ה אֶל־מֹשֶׁ֥ה לֵּאמֹֽר׃
И сказал Господь Моисею, говоря:
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.
