Koren Publishers rethought the nature of prayer when it introduced its Hebrew siddur in 1981. The Koren Classic Siddur features the Koren Book Font, specifically designed by Eliyahu Koren for this Siddur. The Siddur lays out the traditional text in insightful ways that elucidate its underlying meaning. Each word and each line is placed on the page purposefully to enhance kavana.
