עקידת יצחק
Akeidat Yitzchak 98:1
Q — Why does the Torah command bringing bikkurim with a spoken declaration recounting Israel's history? Why pair the first fruits with a recital of the descent to Egypt and the redemption? Why so elaborate a ritual of thanks?
A — The bikkurim and their viduy habituate a person in hakaras hatov — recognizing the good — for the root of all avodah is gratitude for the past. Bringing the first and finest fruit while reciting the whole arc from Lavan and Egypt to the land trains the farmer to trace his present blessing back to its divine Source through history. The ritual converts a private harvest into a national act of thanksgiving, teaching that to serve God begins with acknowledging, concretely and in speech, all He has already done.
