On the face of it, no one reasonably intelligent and well-informed should be shocked by this today. (It still makes news, tho.) But Völter was scorned 100 years ago, made a pariah; his heretical work was buried. Völter was the first to meticulously connect Yahweh w/ Sopdu, for example, yet this linkage remains almost unknown, uncited in scholarly literature. This is the first time I'd seen his detailed arguments based on Egyptian material (which could be updated, fine-tuned w/ discoveries of the past 100 yrs.) so I suppose it's worth sharing.
I am still translating the work into English, to put on the Internet Archive. {Edit: Completed.} See one interesting example at D. Völter, Jahwe und Mose im Licht aegyptischer Parallelen [1919], pp.39-40:
Miriam is mentioned as the sister of Moses. The Egyptian archetype of the latter we would recognize in the Sister of Thoth, goddess Sefkhet-Abwy (Sefkhet-Aabut, Seshat), the usual companion of Thoth on monuments 2), as Miriam is of Moses. If Miriam is presented as a prophetess who sings a hymn of victory to the women (Exodus 15:20,21), so too Sefkhet-Abwy has a prophetic character. In a representation from the period of Seti I {1285 BC}, Seshat/ Sefkhet-Abwy is called ‘Mistress of Writing’, who (like her brother Thoth) records with her hand the glory of the king by order of Rê 1). So also Miriam glorifies the victory of Yahweh in Exodus 15:20-1. Brugsch assumes that Sefkhet-Abwy is the first muse mentioned by Plutarch (De Iside et Osiride, c.3), who was at the same time called 'Isis' and 'Justice' (Δικαιοσύνη) in Hermopolis, and who revealed divine things to those who were actually called Hieraphoroi and Hierostoloi 2).
On the Egyptian goddess assumed the prototype for Jewish Miriam, see Noha Mohamed Hafez, "The Scenes of Sefkhet-Abwy at The Temples" (JAAUTH) Vol. 21, No. 1, (December 2021), pp.1-24.
