More views of Genesis

Interpretations of the fal are a passion of mine. I love them all. At least the well considered ones. This article provides to clues to the rest of Genesis.

it very likely that the biblical Sarah was a high priestess from a disappearing matriarchal culture that still existed in Mesopotamia, alongside an emerging patriarchy.
Ancient Mesopotamian priestesses were highly regarded and their offices were essential to the functioning of society. The priestess was responsible for rituals maintaining the fertility of the land and for decisions on how the stores of grain would be shared. To maintain her impartiality, a priestess was not allowed to bear children of her own, lest she favor her own lineage. Hence all the barren women among the matriarchs of Genesis -- they were priestesses in a new land where their ancient prerogatives were being revoked, systematically, by Yahweh.
The heiros gamos, or sacred marriage, was the supreme fertility ritual performed by a priestess with a king. As the priestess embodied Inanna, Queen of Heaven, she would "take the earth-king into the sweetness of her holy loins, and by her cosmic powers ensure the king's powers of leadership and fertility." This explains the two episodes with Sarah and the kings and another one later between Sarah's daughter-in-law Rebekah and a king. Sarah's first liaison with Pharaoh brings down plague and God makes sure that the second of Sarah's sacred marriages, with King Abimelech, is never consummated. Even the threat of it has made all the women in the kingdom barren and God only restores their fertility after Abimelech sends Sarah back to her husband.
And yet, the repudiation of matriarchal power is not complete. Although multiplying Abraham's seed is the driving thrust of the Genesis story, only the descendents of Sarah's child, Isaac, are counted among the twelve tribes of Israel. Even God backs Sarah up when he lets her banish Abraham's son Ishmael.
