>>1580550>>1581082not the OP, Lilith is not from the Hebrew Bible or new Testament, rather she's from the Midrash, or Jewish legends that the rabbis of the last centuries BCE-first centuries CE told to explain aspects of the old testament with moral lessons.
http://www.jewishencyclopedia.com/articles/9986-lilithhttps://en.wikipedia.org/wiki/Alphabet_of_Sirachall the later stories involving her come from the Talmud, which seem to refer to Liliths (plural) as some sort of Jinn. There's one reference to Liliths in connection with Adam, but not as his first wife before Eve. Instead, Adam begets various demons (including Liliths). There are somewhat vague references to there being multiple Eves in midrashic literature, but they don't make a connection to Lilith.
Christianity does not place any kind of theological importance on the idea of Adam having a "first wife" before Eve, and Lilith's existence is not taught in most Christian denominations (which makes sense since Christianity was already an established religious tradition with its own theological teachings by the time Lilith began to be tied to the Genesis story); however for someone reason very very stupid people tried to reclaim her as some sort of deep symbol of women's power against patriarchal power, when the first story involving her rejecting Adam being on top comes from 9th century from a mystical anonynous Jewish text, so she would have played no part in the early Abrahamic theology
