Paradox #1
Psalms 28:4 asks God to repay people according to their actions. Some might see a contradiction with the teaching of forgiveness and mercy found elsewhere in the Bible, like Jesus' teachings to love your enemies and forgive others. This could seem inconsistent because one part emphasizes justice, while another emphasizes mercy and forgiveness.
Paradox #2
The moral conflict in that verse might relate to the idea of wishing harm or retribution upon others, which could be seen as conflicting with teachings about forgiveness and love for one's enemies in other parts of the Bible.
