If He had drowned our oppressors in it, and had not supplied our needs in the desert for forty years Dayenu, it would have sufficed!

Ilu shika tzareinu b’tocho, v'lo sipeik tzorkeinu bamidbar arba'im shana,  dayeinu

אִלּוּ שִׁקַע צָרֵינוּ בְּתוֹכוֹ וְלֹא סִפֵּק צָרַכֵּנוּ בַּמִּדְבָּר אַרְבָּעִים שָׁנָה דַּיֵּנוּ
