“ Mishnah 1
On the eve of Passover [from] close to [the time of] the afternoon offering,
no one must eat until nightfall.
Even the poorest person in Israel must not eat [on the night of Passover] unless he reclines. ”

“ Unleavened bread [is eaten] because our ancestors were redeemed from Egypt.
[The] bitter herb is [eaten] because the Egyptians embittered the lives of our ancestors in Egypt.
In every generation a person must regard himself as though he personally had gone out of Egypt, as it is said:
“And you shall tell your son in that day, saying: ‘It is because of what the Lord did for me when I came forth out of Egypt.’”
Therefore it is our duty to thank, praise, laud, glorify, exalt, honor, bless, extol, and adore Him Who performed all these miracles for our ancestors and us ”
