Contradiction with Proverbs 24:17
Advises not to rejoice when your enemy falls or stumbles, going against David's advice to deal wisely with Joab's wrongdoing.
Proverbs 24:17: Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth:
Contradiction with Romans 12:19
Encourages leaving vengeance to God, contradicting the instruction to take action against Joab for his actions.
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
Teaches to love your enemies and pray for those who persecute you, which contrasts with taking action against Joab.
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;
Paradox #1
The potential doctrinal conflict in 1 Kings 2:6 could arise from its depiction of King David advising Solomon to act with discernment in dealing with Joab's past actions, which some might interpret as endorsing retaliatory justice. This could seem inconsistent with other biblical teachings that emphasize forgiveness and leaving vengeance to God.
Paradox #2
The moral conflict in this verse could be seen in the advice to act with wisdom while also suggesting a violent or vengeful action. This raises questions about the morality of wisdom being used to harm others, creating a conflict between the principles of justice, mercy, and forgiveness.
