Biblical scholars have long grappled with the troubling Genesis narratives where Abraham and Isaac present their wives as sisters to foreign rulers - passages that seem to condone deception and raise challenging moral questions. Rather than dismissing these stories as primitive morality or defending them uncritically, a dual analytical approach reveals sophisticated literary and strategic dimensions previously overlooked. Steven Brams' biblical game theory demonstrates how the patriarchs transformed extreme vulnerability into strategic advantage through calculated role changes, while Jacob Neusner's structural-anthropological method illuminates the text's carefully constructed motivations and concerns. Comparative analysis of the three parallel passages (Genesis 12:10-20, 20:1-18, and 26:1-11) reveals an interlocking narrative structure that addresses territorial claims, treaty relationships, and the transformation of vulnerability into power. The passages ultimately convey nuanced messages about the temporal limits of personal treaties, the potential for weakness to become strength, and divine protection ensuring relational integrity despite adverse circumstances. This methodology preserves the sacred nature of the text while maintaining intellectual rigor, offering a viable alternative to both fundamentalist and dismissive approaches to difficult biblical narratives.
