Adam speaks of prayer and which parts of Creation praise God each hour of the day; he then prophesies both the coming of the Messiah and the Great Flood; and finally, a description of the celestial hierarchy of angels is given.
There appears to be a quotation of the work in the Syriac version of the Transitus Mariae, generally thought to date to the late 4th century.
[1] The text is pseudepigraphically attributed to Adam's son Seth, who wrote the Testament then sealed it in the Cave of Treasures.
He tells of the creation and fall of man, speaks of the coming Great Flood, prophecies of the Passion of Jesus Christ, and the final end of the world.
[1] The third section, called the Hierarchy by Robinson, includes a detailed angelology that describes all nine orders of angels and their functions.
The text describes one as riding a red horse and killing thousands under the Assyrian king, along with a reference to the 2 Maccabees version of the Battle of Beth Zur where an angel armed with a golden weapon helped send the Seleucid army to flight.
The work (along with the Syriac version of Cave of Treasures) seems to have influenced the Arabic Apocalypse of Peter, another pseudepigraphical text popular in Syrian Christianity dated to the 9th–10th centuries.
