In the first half of the 18th century, Dov Ber of Mezhirich (the Great Magid) lived in Korets, a disciple of Baal Shem Tov, at the behest of which Dov Ber headed the Hasidic movement, that is, Korets became the center of Hasidism after the death of Rabbi Israeli (Baal Shem Tov). Since then, most Jews in Korets have been Hasidim. One of the popularizers of Hasidism was Rabbi Pinhas Shapiro, who settled in Korets in 1760 and later became known as Rabbi Pinhas of Korets.
The Hasidic culture in the city suffered great losses during World War II and the graves of 3 tzadiks were preserved in Korets: Rabbi Asher Zvi (a disciple of Dov ber from Mezhirich, author of the work,” Maayan ha-Khokhma”), Rabbi Yitzhak Izaak ha-Cohen (a disciple of Dov ber, Magid from Mezhirich, author of, "Brit Kegunat Olam") and Rabbi Mordechai, Chairman of the religious court. At kirkut there is a spring,”Jewish tears". It got its name from local residents, because it began to beat after the mass shootings of Jews during the Holocaust. At the same time, the source has one of the best chemical and physical indicators of water in the locality.
