To be inserted after discussing the Pesaḥ offering.

A millennium-old tradition, recorded by Rav Sherira Gaon in 10th-century Iraq. He would always have three cooked foods on the seder plate. The egg, a product of the birds of the sky, a sign of renewal and rebirth, represented Moses, the law, the heavens, and the revelational aspects of faith. The shankbone, a product of the animals of the field, a commemoration of the original Pesaḥ sacrifice, represented Aaron, the priesthood, the earth, and the ritual aspects of faith. And the fish, representing the constant flowing nature of water, represented Miriam, prophecy, the waters, and the spiritual aspects of faith.

We read, as Rav Sherira suggested, Micah 6:4:

“For I brought you from the land of Egypt,
and from the house of bondage redeemed you;
and I sent before you Moses, Aaron, and Miriam.”

And we read Psalms 8:8-10:

The flock and the oxen all,
as well as the animals of the field.
The birds of the skies and the fish of the seas,
traveling the path of the sea.
Oh Adonai Adoneinu, how awesome
is Your name throughout the earth!

And we read from the Talmud (Sotah 11b):

Taught Rav Avira: “In the merit of the righteous women of that generation Israel was redeemed from Egypt. When they would go out to draw water, the blessed Holy One would make for them small fishes in their pails, and they would draw half water and half fishes and would come home and pour two pots – one of boiling water and one of fish.”
