I can’t remember where I saw an explanation why they rushed out of mitzrayim without any food, but it was something to the effect of: Originally the yidden were all packed & ready to leave right after Makkas Dam. Then it cam and went, and nothing happened. Then came Makkas Tzefardayah, they repacked and got ready to leave. Again, nothing happened. Note: they had no idea that there would be a series of makkos, let alone TEN of them. So you can iimagine after makka # 5, and #6, they started giving up with the packing, making sandwiches, etc. How many times were they expected to pack, unpack, pack, unpack, pack, unpack,…???! So when the actual time came to leave in a blink of an eye, they weren’t prepared for the real thing! They didn’t even have food!
Anyone hear of such a thought?
