In religio-mythology, god-to-prophet is a god reduction technique, employed prominently by Hebrew theologians, wherein previously defined “gods” and goddess, e.g. Ra, Isis, Osiris, are rescripted into the literary guise of being famous patriarch-like humans, e.g. Abraham, Sarah, Moses, etc., who tended to be described as being in close communication with the divine.
In c.500BC, Hebrew theologians, most of whom were senior Egyptian priest-teachers called "Choens" (Herodotus, 450BC), in efforts to make a reformed stable monotheism out of the extant henotheism of the dominate cultural milieu, instead of jettisoning all the main gods, such as attempted by Akhenaten (c.1335BC), rescripted the creation story to the effect that the main gods and goddess became human prophets and leaders in story form; the following table, third column, shows the six main Jewish god-to-human rescripts: 
In 1858, Samuel Dunlap, in his Vestiges of the Spirit of Man, citing Franz Movers, who in his The Phoenicians (1841) discusses the mingling and mixing of Greek and Egyptian myths in Phoenicia (c.1100-300BC), stated that the Hebrews were the first to turn the ancient sun gods into patriarchs, therein mediating a de-deification or god reduction: 
“In this way antiquity disposes of its sun-gods. The Hebrews turned [the gods] into Patriarchs. Adam, Abraham, Israel, were names of Saturn. Edom is Adam; and the ancient usage was to name the nation, the land or city after the chief god. The Greeks made these deities founders of tribes.”
A coded literary tool, often employed in the Old Testament, to signify that a god or goddess has been rescripted into the form of a human character, is the description that god has instructed the said person to change their name, e.g. Abram → Abraham (Genesis 17:13-6), Sarai → Sarah (Genesis 17:15-16), or Jacob → Israel (Genesis 32:26-30).
