Contradiction with James 1:26
James speaks about being quick to listen and slow to speak, which contrasts with the idea of testing and trying others.
James 1:26: If any man among you seem to be religious, and bridleth not his tongue, but deceiveth his own heart, this man's religion [is] vain.
Contradiction with Matthew 7:1
While Jeremiah is set as a tester of metals, implying judgment, Matthew advises against judging others.
Matthew 7:1: Judge not, that ye be not judged.
Paradox #1
The contradiction or conflict in this verse could arise from the idea of being tasked to test or observe people, which might conflict with values of privacy and non-judgmental attitudes. It raises questions about the balance between oversight and respecting individual's autonomy or free will.
