Two [individuals] whose pesach-offerings were confused, this one takes one (pesach) for himself, and that one takes one for himself; this one registers some stranger with himself, and that one registers some stranger with himself; this one comes to that [pesach] and that one comes to this [pesach], and they say thus, “If this pesach-offering is mine, [then] you are withdrawn from yours and are registered upon mine; and if that pesach-offering is yours, I am withdrawn from mine and am registered upon yours.”
