The opening as it read in 2025
Aharon ben Jacob Perlov of Karlin (Hebrew: הגדול אהרן בן יעקב פרלוב מקרלין 1736 – 1772), known among the Ḥasidim as Rabbi Aharon the Great , or simply as the "Preacher" or "Censor", was one of the early rabbis of the sect who helped the rapid spread of Ḥasidism in Eastern Europe, and was distinguished for the fiery eloquence of his exhortations. He died one year before his master, Rabbi Dov Ber of Mezeritch , and was succeeded by his disciple, Rabbi Shlomo of Karlin . Rabbi Shlomo was in turn succeeded by Rabbi Aharon's son, Asher. Perlov composed and wrote the famous Sabbath hymn Yah Ekhsof (יה_אכסוף) which is still a widely sung part of the liturgy of the Ḥasidim and has recently become popular among non-Hasidim as well. His ethical will and some collectables are printed in the work of his grandson, Aharon ben Asher of Karlin .
