וַיִּסְע֤וּ מֵֽרַעְמְסֵס֙ בַּחֹ֣דֶשׁ הָֽרִאשׁ֔וֹן בַּחֲמִשָּׁ֥ה עָשָׂ֛ר י֖וֹם לַחֹ֣דֶשׁ הָרִאשׁ֑וֹן מִֽמָּחֳרַ֣ת הַפֶּ֗סַח יָצְא֤וּ בְנֵֽי־יִשְׂרָאֵל֙ בְּיָ֣ד רָמָ֔ה לְעֵינֵ֖י כָּל־מִצְרָֽיִם׃
他們在正月，就是正月十五日，從蘭塞起行。在逾越節的次日，以色列人在全埃及人眼前昂然出去了。
Yalkut Shimoni
"On the morrow of the Passover, the children of Israel went out." It is written, "The Lord your God brought you out of Egypt at night." But did they not go out at night? Was it not during the day? Rather, it teaches us that the redemption began for them in the evening, as it is said, "And this day shall be a memorial for you." It is a day that is a memorial for you, but we did not hear which day it is. When it says, "And Moses said to the people, 'Remember...'," it is still unclear. But when it says, "On the morrow of the Passover, on the fifteenth day of the festival," and they did not go out until the festival day itself, it becomes clear.
