These are the three verses most commonly sung at the Passover Seder. There is a sephardic tradition that during the chorus, participants lightly (key word: lightly) hit each other with scallions.
Ilu hotzi-hotzi'anu hotzi'anu mimtzrayim, hotzi'anu mimtzrayim DAYEINU
Day-dayenu, day-dayeinu, day-dayeinu, dayeinu dayeinu! (dayeinu) Day-dayenu, day-dayeinu, day-dayeinu, dayeinu dayeinu!
Ilu natan natan lanu, natan lanu et ha-Shabat natan lanu et ha-Shabbat dayeinu!
