In the face of imminent death, a desperate act of obedience, though flawed, averts disaster. This reveals a profound truth about God's response to genuine, albeit imperfect, repentance.
The crisis is resolved not by Moses himself, but by his wife, Zipporah, who takes swift, albeit forceful, action.
A Wife's Intervention
Zipporah, understanding the gravity of the situation (likely through divine revelation or Moses's own distress), circumcises their son. The text notes she used a "sharp stone," indicating a hasty, perhaps even reluctant, execution of the rite.
God's Propitiation
Immediately following the circumcision, God's anger ceases. This demonstrates that while the covenant sign was neglected, its proper execution—even under duress and performed by Zipporah—served to appease God's wrath and restore Moses's life.
Imperfect Obedience's Place
This isn't an endorsement of sloppy obedience. However, it shows that God, in His mercy, can respond to a timely, corrective action born out of crisis. Zipporah's act, while potentially filled with indignation (as indicated by her words in v. 25), was ultimately obedience that turned God's judgment aside. It highlights that God desires our obedience, and even a faltering step towards it in a moment of desperate need can demonstrate a yielding to His authority.
