Shefokh hamatkha (“pour out your wrath”) is a prayer recited by Jews at the Passover ritual feast (Seder), where they call for divine punishment of disobedient Gentiles:
Pour out Your wrath upon the nations [Goyim] that do not acknowledge You,
and upon the kingdoms that do not call upon Your Name.
For they have devoured Jacob and laid waste his habitation.
Pour out Your indignation upon them,
and let the wrath of Your anger overtake them.
Pursue them with anger,
and destroy them from beneath the heavens of the Lord.
Joseph Dov Soloveitchik describes it this way in the book “Festival of Freedom: Essays on Pesah and the Haggadah”:
