Ramban on Exodus 13:2/רמב"ן על שמות י״ג:ב׳
אוְטַעַם קַדֶּשׁ לִי שֶׁיְּקַדֵּשׁ אוֹתָם מִיָּד, שֶׁתִּהְיֶה הַמִּצְוָה נוֹהֶגֶת בַּמִּדְבָּר. וְהוֹסִיפָה הַפָּרָשָׁה מִצְוֹת רַבּוֹת שֶׁיִּזְכְּרוּ הַיּוֹם וְהַחֹדֶשׁ שֶׁיִּהְיֶה אָבִיב, וְיִשְׁמְרוּ אֶת הַחֻקָּה הַזֹּאת לְמוֹעֲדָהּ, וְזֶה רֶמֶז לְעִבּוּר הַשָּׁנָה כִּי לֹא נַעֲשֶׂה פֶּסַח רַק בְּחֹדֶשׁ הָאָבִיב, וְהוֹסִיפָה בֶּחָמֵץ "לֹא יֵרָאֶה לְךָ שְׂאֹר בְּכָל גְּבוּלֶךָ", וּמִצְוַת הַטּוֹטָפוֹת:
1SANCTIFY UNTO ME. This means that they are to consecrate the firstborn at once so that the commandment be applicable in the wilderness. This chapter adds many commandments: that they remember the day [when they left Egypt] and that the month was Aviv,364 and that they keep this ordinance in its season.365 This is an allusion to the intercalation [of an extra month] in the lunar year,366 since we are to observe the Passover only in the month of Aviv, [which is the spring]. On the subject of leavened bread, this chapter adds: Neither shall there be leaven seen with thee, in all thy borders.367 At the conclusion, it adds the commandment of the frontlets.368
