This chapter explores the wisdom of Genesis 23, according to the Hebrew hermeneutic traditions. The chapter tells about the purchase of the Cave of Makhpela in Hebron by Abraham to bury his wife Sarah. This chapter develops the current relevance of this narrative as a systemic response to the limitations of the Aristotelian and Cartesian concepts of definition, boundary and identity. Hence, there is wisdom in Genesis 23 for our times, where boundaries are blurred and globalization leads to confusion. Meeting at the boundaries is always a "marginal" activity but an essential one to create sustainable wealth.
