The Koren Sacks Siddur is the first new Orthodox Hebrew/English siddur in a generation. The siddur exemplifies Koren's traditions of textual accuracy and intuitive graphic design, and offers an illuminating translation, introduction and commentary by one of the world's leading Jewish thinkers, Rabbi Jonathan Sacks.

It is the only Orthodox siddur that includes: prayers for the state of Israel, its soldiers and national holidays, and a halakhic guide for visitors; prayers following childbirth and upon the birth of a daughter; a modern translation , and citations of modern authorities. Also included are prayers for the US and Canadian governments.
