Richard E. Friedman writes that since Cush is generally understood to mean "Ethiopia", it is possible that the "Cushite woman" is not Tzipora. But he adds that since there is a place called Cushan which is a region of Midian, and Moses’ wife Tzipora has already been identified as a Midianite, it is possible that the term "Cushite" relates to Tzipora's being from Cushan. However, Friedman's primary interest is not in the identity of the Cushite woman, but rather in the outcome of this story which establishes Moses' superiority over Aaron as an example of his claim that rival priesthoods created or publicized tales in order to legitimize their respective claims to privilege and power. He describes the Aaronid priesthood in the Kingdom of Judah, which claimed descent from Aaron and which controlled the Temple in Jerusalem, as opposed to a priesthood which claimed allegiance to Moses and was based at Shiloh in the Kingdom of Israel. Using interpretations from the documentary hypothesis, he notes that this story, which he calls "Snow-White Miriam", was authored by the Elohist who he claims was from, or supported, the Shiloh priesthood, and thus promoted this tale to assert Moses’ superiority over Aaron and thereby belittle the Aaronid priesthood in Judah. However, the identity of the Cushite woman referred to in this story is tangential to Friedman and his opinion remains inconclusive.
