In De Principiis III.2.1, Origen writes:
"We have now to notice, agreeably to the statements of Scripture, how the opposing powers, or the devil himself, contends with the human race, inciting and instigating men to sin. And in the first place, in the book of Genesis, the serpent is described as having seduced Eve; regarding whom, in the work entitled The Ascension of Moses (a little treatise, of which the Apostle Jude makes mention in his Epistle), the archangel Michael, when disputing with the devil regarding the body of Moses, says that the serpent, being inspired by the devil, was the cause of Adam and Eve’s transgression."
Origen believed that Jude invoked The Ascension of Moses (also known as The Assumption of Moses) when he mentioned the Devil having a dispute with Michael over the body of Moses.
De Principiis is also called Peri Archon in Greek.
