Al hanissim v’al hapurkan

V’al hanifla’ot she’asita la’avoteinu
Bayamim hahem bizman hazeh

Hebrew:

וְעַל הַנִסִּים, וְעַל הַפֻּרְקָן,
וְעַל הַגְבוּרוֹת, וְעַל הַתְּשׁוּעוֹת,
וְעַל הַנִפְלָאוֹת, שֶׁעָשִׂיתָ לַאֲבוֹתֵינוּ
בַּיָמִים הָהֵם בִּזְמַן הַזֶה.

Translation:

[We thank You G‑d] For the miracles, the redemption,
the mighty acts, the saving acts and for the wonders
that You have done for our fathers, in those days at this time.
