Paradox #1
Joshua 2:19 could present a moral conflict related to collective punishment. The verse implies that if certain individuals leave a particular area, they are responsible for their own fate, rather than the group facing consequences for individual actions. This can be seen as contradicting the idea of individual accountability, as it suggests that others could be punished for the actions of a few or because they left a designated area, even if they themselves did nothing wrong.
