Contradiction with Proverbs 27:6
This verse states, "Faithful are the wounds of a friend; but the kisses of an enemy are deceitful," which contradicts 2 Samuel 20:9 as Joab's friendly gesture to Amasa was deceitful and led to murder, not faithfulness.
Proverbs 27:6: Faithful [are] the wounds of a friend; but the kisses of an enemy [are] deceitful. [deceitful: or, earnest, or, frequent]
Contradiction with Matthew 5:44
This verse instructs, "But I say unto you, Love your enemies, bless them that curse you," which contradicts Joab's act of betrayal and murder of Amasa, rather than an act of love or blessing.
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 Romans 12:17
This verse advises, "Recompense to no man evil for evil," contradicting Joab's act of deception and violence in response to Amasa's potential threat.
Romans 12:17: Recompense to no man evil for evil. Provide things honest in the sight of all men.
Contradiction with Exodus 20:13
This commandment states, "Thou shalt not kill," directly contradicting Joab's action of killing Amasa.
Exodus 20:13: Thou shalt not kill.
Paradox #1
The contradiction in this passage might be that it involves deceit and betrayal. Someone shows outward signs of friendship or peace, like a friendly gesture, while secretly planning harm. This action goes against the moral teaching of honesty and trust.
