Мидраш к Шмот 13:3

Similarly, though Scripture states: And the priests shall kindle wood upon it every morning (Lev. 6:5), it is written: And Lebanon is not sufficient fuel (Isa. 40:16). This was stated so that one might receive a reward for doing so. Similarly, it says: The one lamb thou shalt offer in the morning (Num. 28:4), though it has already been said: Nor the beasts thereof sufficient for burnt-offerings (Isa. 40:16). This indicates that you may receive a reward (for its observance). Let them make Me a Sanctuary that I may dwell among them (Exod. 25:8) may be explained in a like manner. Has it not been written already Do not I fill heaven and earth (Jer. 23:24)? This commandment was imposed upon you so that you would receive a reward (for building a Sanctuary). And Moses said unto the people: Remember this day (Exod. 13:3). Scripture states elsewhere: That thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life (Deut. 16:3). Does this mean that they were to remember it only during the day and not at night? Ben Zoma interpreted the verse That thou mayest remember the day when thou came forth … all the days of your life to mean that the days of your life refers to the daytime, while all the days of your life alludes to night time.

Yosé the Galilean said: From the fact that Scripture states: There shall no leavened bread be eaten, and adds immediately thereafter, this day you shall go forth (ibid., v. 11), you may deduce that the Israelites ate unleavened bread in Egypt on only one day. In the month of Abib. This is the perfect month, being neither to hot nor too rainy. Whence do we know that it is the perfect month? it is written here: The month of ripening (abib), and elsewhere it is written: God maketh the solitary to dwell in a house; He bringeth out the prisoners into prosperity (Ps. 68:7). And the word bekosharot (“prosperity”) refers only to the ideal month which is neither too hot nor too rainy (for the ripening of the harvest).¹⁵A play on words: bekosharot (“prosperity”) and kasher (“fitting”)
