Contradiction with Matthew 5:44
Jesus instructs to love your enemies and bless them, rather than merely offering peace to those already in favor, like in 1 Samuel 25:6.
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 Luke 6:27
Calls for love and good actions towards enemies, not just peaceful greetings to allies.
Luke 6:27: But I say unto you which hear, Love your enemies, do good to them which hate you,
Contradiction with Proverbs 25:21

Contradiction with Romans 12:20

Contradiction with Romans 12:18
Urges to live peaceably with all men, not just select individuals, broadening the directive in 1 Samuel 25:6.
Romans 12:18: If it be possible, as much as lieth in you, live peaceably with all men.
