In the biblical narratives associated with her, Miriam emerges through profiles that are not fully overlapping, whose configuration remains consistently related to the negotiation and maintenance of Moses' authority. In the first episode of the exodus narrative traditionally associated with her figure (Ex 2), Miriam is introduced without a name, as a "sister" watching from the bank of the Nile, within a scene shaped by the threat exercised by a dominant power over the most vulnerable. Embedded in a network of female initiatives that resist the resulting logic of death, her action forms part of the narrative background that enables the emergence and survival of the protagonist, Moses. In another section of the narrative Miriam is remembered as a figure invested with a prophetic role; yet this investiture is expressed in a choral and relational form, within a narrative that continues to concentrate authoritative voice and normative legitimacy on Moses. The coexistence of these characterizations is accompanied by textual tensions that resist easy harmonization and that a long interpretive tradition, ancient and modern, has recognized as traces of a complex narrative negotiation of authority. This dynamic becomes particularly visible in the narratives that associate Miriam with a critical speech challenging Moses' leadership. Here, her authority is exposed as potentially competing with the exclusive authority of the leader; the asymmetrical punishment and the subsequent narrative silencing function as mechanisms that regulate the visibility and limits of her role. Alongside this restrictive configuration, however, the biblical text also preserves attestations that include Miriam among the leaders sent by God together with her brothers (Mic 6:4), while a broad and diverse interpretive tradition has continued to re-engage her figure. In their interplay, these elements continue to yield a figure whose memory unfolds through superimpositions, disalignments, and rewritings.
