Found in: Exodus 4:24-26
Continuing the Bible’s fascination with all things foreskin, we get the bizarre story of God trying to kill Moses because his son isn’t circumcised. God is about to obliterate Moses when his wife Zipporah takes out a flint and quickly cuts the foreskin of his son (ouch), throwing the bloody skin fragment at Moses’ feet. “You are a bloody husband to me!” squeals Zipporah, flint in one hand, child in other. God, clearly freaked out by this woman, backs off and Moses is saved.
The moral of this story? Never turn down a woman for being a psycho. Someday she may save your life.
