I took the time to cite ALL the range of meanings of the Aramaic term ḥbr from the CAL website below. As the reader will again see the term is rooted in the concept of the act of 'joining' or joining an association but there is a specifically Biblical derived meaning of the term which denotes someone who 'binds' or 'associates' with demons. So we start with the Anchor Bible Dictionary for instance has the following entry for the term:
One who is a spellbinder (ḥōbēr ḥāber). Scholars generally agree that the root ḥbr refers to the use of charms and spells since the root conveys the idea of “uniting, joining, and weaving,” which may by
extension speak of the practice of “tying or wrapping magical knots or threads around people or objects . . . to bind the gods to do one’s will or to bind (disable) the object or person to be affected. [David Noel Freedman, The Anchor Bible Dictionary (New York: Doubleday, 1996, c1992), 4:468]

So when we return to the description of Irenaeus it is impossible not to see the range of meanings here. Indeed the fact that Irenaeus cites Aramaic Marcosian prayers later in the report demonstrates that both Irenaeus and his subject matter were familiar with the language.
