Contradiction with Proverbs 15:1
While Psalms 109:2 speaks of deceitful and hateful speech, Proverbs 15:1 encourages gentle answers to turn away wrath.
Proverbs 15:1: A soft answer turneth away wrath: but grievous words stir up anger.
Contradiction with Ephesians 4:29
Contradicts by promoting speech that is good for edifying and avoids corrupt communication.
Ephesians 4:29: Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers. [to...: or, to edify profitably]
Contradiction with Matthew 5:44
Encourages believers to love their enemies and bless those who curse them, opposing Psalms 109:2's theme of animosity.
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 Colossians 3:8
Advises against wrath, malice, and filthy communication, which contrasts with the tone of false and deceitful speech in Psalms 109:2.
Colossians 3:8: But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
Contradiction with James 1:26
Highlights controlling one’s tongue as a mark of true religion, contrasting with the deceitful speech in Psalms 109:2.
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 1 Peter 3:9
Instead of returning evil for evil or reviling for reviling, believers are encouraged to bless, which opposes the notion of deceitful words.
1 Peter 3:9: Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing.
Paradox #1
Psalms 109:2 talks about facing deceitful and lying people. The contradiction might be found in the broader context of the psalm, where it expresses a desire for punishment against enemies. This could conflict with the teachings of forgiveness and love for one's enemies found in other parts of the Bible.
