The Itureans were a northern Levantine people associated with the Lebanon and Anti-Lebanon region. Hasmonean expansion under Aristobulus I is reported to have drawn parts of this population into Jerusalem-oriented political and ancestral law structures. The surviving sources are brief and shaped by elite political concerns, so the process should be read as regional incorporation rather than a clean mass religious event.

Their inclusion matters because it shows the porous edges of the Second Temple-era polity. Yahweh allegiance could expand through conquest, alliance, local elite negotiation, and legal incorporation. The stream is Abrahamic color because it is a cultural-conversion branch rather than a sectarian split.
