Based on the Koren Shalem siddur, with translation and commentary by Rabbi Lord Jonathan Sacks zt"l, the Koren Kol Yaakob Siddur has been adapted for the Syrian community from Aram Soba. Like the Koren Shalem Siddur, the Koren Kol Yaakob contains full prayer services and Torah readings for weekdays, Shabbat, and festivals in both Hebrew and English along with extensive sections for life-cycle events, berakhot, personal supplications, and more.

Aram Soba traditions are based on those of the community from modern-day Syria which dates back to the days of King David.
