Book of Jubilees
The Book of Jubilees similarly has Isaac telling Levi of the future of his descendants, again predicting priesthood, prophets, and political power, and additionally describes Jacob as entrusting Levi with "the secrets of the ancients", so that they would be known only to the Levites; however, like the Testament of Levi, the Book of Jubilees is regarded as a Maccabean-era document.
