Exodus 12:16

מקרא קדש — The word מקרא is an infinitive and the translation is, “And on the first day there shall be “a calling it holy”, which implies: call it holy in regard to eating and drinking and raiment (Mekhilta). לא יעשה בהם NO WORK SHALL BE DONE ON THEM, even by the agency of others (cf. Mekhilta). הוא לבדו THAT ALONE — that and not such acts preliminary to it (to the preparation of food) as it was possible to do on the eve of the Festival (Beitzah 28b). לכל נפש BY EVERY BEING — even by cattle. One might think that also food may be prepared for non-Israelites! Scripture however states, (in this verse) לכם (i. e. לכל נפש לכם) for every being that belongs to you (the responsibility for feeding which belongs to you) (Mekhilta).

And on the first day there shall be a holy gathering, and on the seventh day there shall be a holy gathering to you; no manner of work shall be done on them, save that which every person must eat, that only may be done by you.
