וַיֹּאמֶר יְהוָה אֶל־מֹשֶׁה עֹוד נֶגַע אֶחָד אָבִיא עַל־פַּרְעֹה וְעַל־מִצְרַיִם אַחֲרֵי־כֵן יְשַׁלַּח אֶתְכֶם מִזֶּה כְּשַׁלְּחֹו כָּלָה גָּרֵשׁ יְגָרֵשׁ אֶתְכֶם מִזֶּה׃
Shemot 11:1
Arcana Coelestia # 7897
7897. 'And you shall observe [the feast of] unleavened bread' means that there must be no falsity. This is clear from the meaning of 'unleavened bread' as what has been purified from all falsity, dealt with in 2342.
