Paradox #1
The potential contradiction in Ezekiel 9:8 could be the idea of divine justice versus mercy. On one hand, the execution of judgment may seem just, but on the other hand, it raises questions about the lack of mercy for those who might be innocent or repentant. This tension between justice and mercy can be seen as a conflict within the context of the verse.
