The Manna Machine is a 1978 book by George Sassoon and Rodney Dale, based upon a translation of the section of the Zohar called The Ancient of Days that concludes that a machine had created algae as food for human beings in biblical times.

[citation needed] The machine was reproduced by Sassoon who was an engineer, who followed the directions given in The Ancient of Days and he claimed it created a food source of algae.

This explains how the Israelites survived their forty-year journey in the Sinai Desert.

It is said by Sassoon and Dale that a nuclear reactor used to power the manna machine was stored within the Ark of the Covenant.

This knowledge was preserved within the Jewish Kabbalah that the authors claim to have correctly decoded.
