A tradition preserved in some midrashic sources identifies Pinchas, granted a covenant of peace for his zeal, with the prophet Elijah, holding that Pinchas was granted an unusually long or even eternal life and later appeared, or returned, as Elijah; the identification is aggadic rather than a claim most classical legal authorities treat as binding, and other rabbinic sources keep the two figures entirely distinct, so the tradition is best understood as one strand of legend among several rather than a settled genealogical claim.
Pinchas also repeats, with some differences of quantity and detail, a festival sacrificial calendar already given in Emor (Numbers 28-29, compared to Leviticus 23), a doubling source critics read as evidence that the Priestly source preserved more than one register of festival law, a shorter, calendar-focused list here concerned with the specific animals and quantities offered on each occasion, alongside Emor's broader list organised around each festival's meaning and timing, both retained in the final Torah rather than harmonised into a single list.
The second census Pinchas records (Numbers 26) is not merely a headcount: the text ties the results directly to inheritance, instructing that the land be allotted among the tribes in proportion to each tribe's counted size, larger tribes receiving a larger share and smaller tribes a smaller one (Numbers 26:52-56), so that this portion's census functions as the legal basis for the territorial division Joshua later carries out rather than as an administrative record kept for its own sake.
