Why did the angel seek to kill Moses for failing to circumcise his son if that omission does not carry the death penalty?

This source-based Torah study examines the question: Why did the angel seek to kill Moses for failing to circumcise his son if that omission does not carry the death penalty? The canonical Hebrew discussion develops the issue through the weekly Torah portion and the classical sources cited there, preserving the distinctions and tensions of the original unit. This localized layer is a discovery-oriented summary rather than a full translation of the article, and it does not add a new halakhic, medical, legal, historical, mystical or empirical ruling or claim beyond the canonical source. Any practical conclusion remains subject to the unit’s canonical review status.
