It is a Yiddish Lullabye. I can't remember the words. There is a book called "Roesinke und Mandeln" (meaning Raisins and Almonds) published in German which has that and many other Yiddish songs. I don't have a copy anymore.In the Orthodox synagogue, in those old sexist days,the women were not allowed in the main area, but they had a "peanut gallery" up above. There was one ceremony, where the little boys are supposed to have reached a certain point in their religious development (not the Bar Mitzvah--that is when they are no longer little boys.) The women shower the little fellers with small bags of raisins and almonds from above. It is a traditional gift for boys who reached that stage.
So the lullabye is the mother telling her infant son how proud she will be of him someday.
I am really embarassed at not remembering more about it. I actually took part in the ceremony when I was a child.
