Is the Testament of Solomon Biblical? Okay so I was looking around on google for some answers about where some of the demon names that are "Biblical" came from, and I came across the Testament of Solomon. It isn't in the Bible from what I can tell. (It may be, if so, can I have some references?). It is an account of how Solomon enslaved demons using Michael's ring and made them rebuild the temple. There's something about all of this that just feels off. Does anyone know if its considered true by the majority or if its just considered untrue?
In broad strokes, the term "Biblical" gets used in one of two senses:


Content included in or coming directly from the canon of the Bible.
Something that is in essential agreement with what the Bible teaches about a subject.


The so called Testament of Solomon is Biblical in neither of these senses. It is not included in anybody's canon (not the Jews, Catholics, Protestants, any of the Orthodox churches, or any of the more recent denominations). In other words no branch of Christianity considers the work authoritative. Additionally its content directly contradicts the Biblical narrative of the same events on many points.
