וְאָכְל֥וּ אֶת־הַבָּשָׂ֖ר בַּלַּ֣יְלָה הַזֶּ֑ה
And they shall eat the flesh in that night.
וְלֹא־תוֹתִ֥ירוּ מִמֶּ֖נּוּ עַד־בֹּ֑קֶר וְהַנֹּתָ֥ר מִמֶּ֛נּוּ עַד־בֹּ֖קֶר בָּאֵ֥שׁ תִּשְׂרֹֽפוּ׃
And ye shall let nothing of it remain until the morning; but that which remaineth of it until the morning ye shall burn with fire.
B'nai Yisra'el left Egypt early in the morning, they were told to leave in a hurry, and the Torah says that they were chased out and had to leave so quickly that they didn't prepare food nor did they have time to let the dough rise.
What happened to the left over Pesach lamb? Was there absolutely no left over with anyone at all? If there was, when did they have time to burn it?
