Deuteronomy 27 is usually regarded as an awkward chapter, both internally as well as in its relationship to the chapters preceding and following it. It is the purpose of this article to discuss the theology of this chapter. The relationship of Yahweh and Israel to each other is discussed, with focus on Israel under curse and under grace. Rather than offering two equally possible options, blessing and curse, the ceremony on Mount Ebal is biased towards curse. No blessings are mentioned.
