I've searched all related data on this choral incident in Italy. From the reasoning that it was the song that both Peiper and the disliked local Nazi official knew, we can assume that it(or they) was a very well-known Jewish hymn.5. What was the Jewish traditional song that Jews sang in front of the billet of that Nazi official?
I believe that at least one of the following four hymns was sung by the Jewish rabbis rescued by Peiper on that day before the billet of the local Nazi official.
Adir Hu (He is Mighty)
Adir Hu is a sing-along song with a catchy tune and is generally sung as the Seder comes to a close. This Jewish hymn expresses hope that the age of Messiah will return and the sacred Temple will be rebuilt. In Hebrew, each line of this hymn starts with a different letter of the alphabet in alphabetical order.
He is mighty, He is mighty
Chorus:
May He soon rebuild his house.
Speedily, speedily and in our days, soon.
G-d, rebuild! G-d, rebuild!
Rebuild your house soon!
He is distinguished, He is great, He is exhalted
(Chorus)
He is glorious, He is faithful, He is faultless, He is righteous
(Chorus)
He is pure, He is unique, He is powerful,
He is wise, He is King, He is awesome,
He is sublime, He is all-powerful, He is the redeemer, He is all-righteous
(Chorus)
He is holy, He is compassionate, He is almighty, He is omnipotent
(Chorus)
Dahyenu (It Would Have Been Enough For Us)
One of the most popular Seder tunes, it describes some of the many favors that God bestowed upon the Israelites when He led them to freedom into the Land of Paradise from Egypt. This song has been taken from Haggadah. We have got just two verses of this song for you.
Had He brought us out of Egypt and not judged them,
It would have been enough for us.
(Chorus)
It would have been enough for us.
Had He judged them and not done so to their idols,
It would have been enough for us.
(Chorus)
It would have been enough for us.
Eliyahu Ha-Navi (Elijah, the Prophet)
This song is to be sung when the Cup of Elijah is poured and the door is opened in anticipation of his return.
Elijah the Prophet,
Elijah the Tishbite,
Elijah, Elijah,
Elijah the Gileadite
Speedily and in our days,
Come to us,
With the messiah, son of David,
With the messiah, son of David.
Any additional information would be welcomed.Mah Nishtanah (Why is it Different?)
This number us tune sung when the youngest at the table is reciting the Four Questions.
Why is this night different from all other nights, from all other nights?
On all other nights, we may eat chametz and matzah, chametz and matzah.
On this night, on this night, only matzah.
On all other nights, we eat many vegetables, many vegetables.
On this night, on this night, maror.
On all other nights, we do not dip even once.
On this night, on this night, twice.
On all other nights, we eat either sitting or reclining, either sitting or reclining.
On this night, on this night, we all recline.
