Paradox #1
The verse you mentioned discusses imprudent behavior in financial dealings, particularly in guaranteeing a loan for another person. A possible contradiction could arise in contexts where the Bible also encourages generosity and helping others in need. The inconsistency might be in balancing the caution advised in this verse with the overall biblical message of supporting and loving one's neighbors.
Paradox #2
Proverbs 17:18 could present a contradiction or inconsistency with teachings on charity and generosity. While the verse warns against being surety or guaranteeing another person's debt, other parts of the Bible encourage helping and supporting others in need. This could create a conflict between being cautious with one's resources and being generous and helpful to others.
