The Akedah—Abraham’s near-sacrifice of Isaac in Genesis 22—has long been read as the Bible’s ultimate test of faith and obedience. The Hebrew word means “to tie up” or “to bind,” describing what Abraham does to Isaac in response to God’s command to kill his son. He sets out without telling Sarah, fully intending to murder his child, only for the Lord to intervene at the last moment with a critical message. Abraham’s trial of faith is so devastating that he never again speaks to Isaac, Sarah, or God. Philosophers and theologians have interpreted the story in strikingly different ways: Did God expect Abraham’s obedience—or yearn for his “pious irreverence”? In this interview, scholar Aaron Koller explores the history of interpreting the Akedah, examining what this haunting episode means for readers of faith.
