Journey
In early Germanic societies, an oath was not merely a statement of intent but a legally binding act often involving ritualistic components and divine invocation. The transition from 'solemn promise' to 'blasphemous profanity' reflects the linguistic tendency for words involving holy concepts to be repurposed for intense emotional expression.
