We read the text below.

Pearl Benisch… remembers Passover in the Bergen-Belsen concentration camp in Germany in the spring of 1945, just days before her liberation.
 
“We had nothing to eat but watery soup, with bread once a week,” she told me in a very quiet voice. “But I was one of the lucky ones. I was working in a place where we peeled potatoes and turnips. I cut three turnips in narrow rounds, covered them up with a piece of brown paper and hid them in my shoes.
 
“When we had our Seder in the peeling room with one woman keeping watch for the guards, the other women moaned that there was no matzo. I said, ‘they are here, they are under the cover.’ They opened the brown paper and there were the three round turnip matzos.”
 
Then, Mrs. Benisch, now in her late 80’s, paused and said in a whisper, “Only God can make matzo from turnips.”^[1] Joan Nathan, ‘Bread of Freedom in Times of Despair,’ The New York Times, 16 April 2008. 

The rabbis say that Pesaḥ, the time of the redemption from Egypt, will eventually be the time of the redemption of the earth upon the arrival of the messianic age. When a society as cruel as Pharaoh arose and sought to destroy our people, when the ultimate redemption seemed as far off as ever, we remembered this. Let us remember them as well. Traditional Haggadot include the next three verses. The fourth has been added to end on a more positive, hopeful note.

Pour out Your anger on the nations who do not know You, and on the empires who do not call Your name! For they have devoured Jacob and desolated his abode! (Psalms 79:6-7)

Pour upon them Your fury, and may Your hot anger overtake them! (Psalms 69:25)

Pursue them in anger, and destroy them under the heavens of Adonai! (Lamentations 3:66)

Thus may your enemies perish, Adonai, but may those who love you be as the sun rising in its glory! (Judges 5:31)
