אֲשֶׁ֣ר פִּ֭יהֶם דִּבֶּר־שָׁ֑וְא וִֽ֝ימִינָ֗ם יְמִ֣ין שָֽׁקֶר׃
Których usta mówią fałsz, których prawica, prawicą zawodną.
Mishnah Pesachim
[As to] an onen, and one who is removing a heap [of stones], and likewise one whom they promised to take out of prison, and a sick or an old person who can eat as much as an olive, they slaughter on their behalf. [Yet in the case of] all these, they may not slaughter for them alone, lest they bring the pesah to disqualification. Therefore if a disqualification occurs to them, they are exempt from keeping the second pesah, except for one who was removing the heap, because he was unclean from the beginning.
