Parashas Bo · Passuk 12:47
Chabad.org — English translation + Rashi
Torah Temimah points to see Torah Temimah note (verified).
English: Might it be that just as the Pesach of Egypt was taken only for a family, so too the Pesach of the generations? Therefore it says “the whole congregation of Yisrael shall perform it.”
In context: See the cited source for the full section.
Derash on the verse.
Pesach of the generations may be made by mixed companies, not only single families.
