In every generation a man is bound to regard himself as though he personally had gone forth from Egypt, because it is said, and you shalt tell your son in that day, saying: it is because of that which the Lord did for me when i came forth out of Egypt (Shemot/Exodus 13:8). therefore it is our duty to thank, praise, laud, glorify, exalt, honour, bless, extol, and adore him who wrought all these miracles for our fathers and ourselves; he brought us forth from bondage into freedom, from sorrow into joy, from mourning into festivity, from darkness into great light, and from servitude into redemption.
Therefore let us say before him, “Hallelujah!”
(Babylonian Talmud Pesachim 116a,b)

Did you know that Paul commands us to keep the feast?

Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Messiah, our Passover lamb, has been sacrificed. Therefore let us keep the Feast, not with the old bread leavened with malice and wickedness, but with the unleavened bread of sincerity and truth.
(First Corinthians 5:6-8)
