Seven Holocaust survivors gathered in Toronto on Monday afternoon to restore a Torah scroll that was hidden in a Polish village in 1939.

“I made the decision that the only people who would be rewriting the letters in this Torah — this Torah that survived the Holocaust — would be survivors themselves,” Jonny Daniels told the National Post.

Daniels is the founder of From the Depths, an organization dedicated to Holocaust memory and memorial. The Torah was entrusted to Daniels in 2016 after it was rediscovered in the home of a Polish couple. A Torah, a holy Jewish text, consists of the first five books of the Hebrew Bible, from Genesis to Deuteronomy. Torah scrolls are made of parchment sheets from the hides of kosher animals and written by hand by a scribe, or a sofer.
