The Wives' Tales of Genesis 12, 20, and 26 and the Covenants at Beer-Sheba
This article first gives a survey of scholarship on the study of Genesis 12, Genesis 20, and Genesis 26, passages where Abraham and Isaac claim that Sarah (12:11-16; 20:2-3) and Rebekah (26:6-11) were their sisters. Next, it develops suggestions that have been considered only in passing by a few scholars, and that is that some type of diplomatic marriage may be involved in the stories.
