A Torah that was recovered from Poland after the Holocaust, is currently in the process of being restored, letter by letter.
A Rabbi gave this Torah to his neighbor for safekeeping just before he was taken to the Treblinka concentration camp. Thirty years later, a group of students researching Jewish history in Poland came across the neighbor, who still had the Torah in his possession, albeit in very poor condition. Since its discovery, the Torah has been slowly restored with the participation of many Holocaust survivors, each honored with writing a single letter.
There are 613 mitzvot in the Torah, with the 613th mitzvah being to write a letter in a Torah. This week, on Yom HaShoah, Holocaust Remembrance Day, survivor Avraham Roet wrote a letter. #AmYisraelChai
