beitza 2b - manna on Y"T (2)

More on the topic of whether the manna fell on Yom Tov. We have lechem mishnah as a zecher l’man. We also have a challah cover according to some rishonim as a zecher l’man. It would seem that if the manna fell on Y”T there would be need for neither on Yom Tov. Some rishonim (quoted in Tur), however hold other reasons for the challah cover: perhaps it is “shelo yirah hapas boshto” or “l’kavod shabbos” each of which applies equally to Yom Tov regardless of the manna. Another nafka mina in the reason for covering the challah might be whether it needs a cover on the bottom (if it is a zecher l’man it may need to be surrounded on all sides, according to the other reasons it only needs to be covered on top). Another Nafka mina would be whether it needs to remain covered after kiddush (if it is l’kavod shabbos or zecher l’man yes, if it is not to embarass the bread no.) Another nafka mina may relate to seudah shelishis where there is not kiddush but there is a fulfillment of kavod shabbos and the entire meal is certainly a zecher l’man. Oddly though, on Yom Tov we do lechem mishnah (with the cover) clearly assuming manna did not fall, while we don’t do seudah shelishis (apparently assuming that the manna did fall). See Rabeinu Manoach chameitz umatzah 8:6 who deals with this problem.
