Contradiction with Romans 12:19
This verse advises against seeking revenge, whereas Psalms 9:16 speaks of God executing judgment.
Romans 12:19: Dearly beloved, avenge not yourselves, but [rather] give place unto wrath: for it is written, Vengeance [is] mine; I will repay, saith the Lord.
Contradiction with Matthew 5:44
This verse instructs to love and pray for enemies, contrary to the triumph over enemies in Psalms 9:16.
Matthew 5:44: But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
Contradiction with Ezekiel 18:32
God expresses no pleasure in anyone's death, contrasting with the focus on judgment in Psalms 9:16.
Ezekiel 18:32: For I have no pleasure in the death of him that dieth, saith the Lord GOD: wherefore turn [yourselves], and live ye. [yourselves: or, others]
Contradiction with James 2:13
Emphasizes mercy triumphing over judgment, unlike the direct retribution mentioned in Psalms 9:16.
James 2:13: For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment. [rejoiceth: or, glorieth]
Contradiction with 2 Peter 3:9
Highlights God's patience and desire for repentance, differing from the immediate judgment in Psalms 9:16.
2 Peter 3:9: The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
Paradox #1
The possible contradiction in Psalms 9:16 could be the idea of justice being served through punishment, which might conflict with themes of forgiveness and mercy found elsewhere in the Bible. It raises questions about how justice and mercy coexist.
