Shuvoo means "return". In fact, it is an active verb form meaning "(you) return". It has particular emphasis in a passage written by the Prophet Malachi: "Ever since the days of your fathers, you've turned away from My statutes and haven't observed them. Return (shuvoo) to Me and I will return (ashuvah) to you, says the G-d of Hosts." (Malachi 3:7, JPS Tanach)
Ashirah Yosefa teaches about returning to G-d … the G-d of Israel. It is about returning in truth and clarity, looking back to the foundation of faith for all nations of the world, the Noahide Commandments, and forward to the Torah given by G-d to Moses - the most complete revelation of G-d that can exist in this world until the World to Come.
