Paradox #1
The potential moral conflict in the context of Joshua 2:20 could arise from the idea of deception being used for a perceived good purpose. The broader story involves the use of misleading actions to achieve a strategic advantage, which raises questions about whether ends justify means. Some might see this as conflicting with the value of honesty.
