Seven Universal Laws of Noah for All Mankind
Law 2 of 7
Do not blaspheme the name of God.
The second Noahide Law prohibits blasphemy — cursing, defaming, or speaking contemptuously of God. This law reflects the deep reverence owed to the Creator and guards the sanctity of the divine name in human speech and thought.
Language shapes reality. The way we speak about God reflects the way we relate to Him. Blasphemy is not merely a violation of etiquette — it is an act of rebellion against the very ground of existence. It corrupts the speaker and degrades the shared moral fabric of society.
Conversely, speaking of God with reverence — even in ordinary conversation — elevates both the individual and the community. The prohibition of blasphemy invites us to cultivate a constant awareness that we speak in the presence of the Infinite.
A Noahide should guard their speech carefully, avoiding any expression that mocks, curses, or demeans God. This extends to refraining from using divine names carelessly or in profane contexts. Developing a habit of reverent speech — even silently — is a positive fulfillment of this law's spirit.
