Contradiction with Matthew 5:44
Jesus instructs to love and pray for enemies, in contrast to Job 31:30 where Job claims he did not curse his enemy.
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 Proverbs 24:17
Advises not to rejoice or be glad when your enemy falls, which is a broader stance than Job 31:30's claim of not cursing an enemy.
Proverbs 24:17: Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth:
Contradiction with Romans 12:14
Encourages blessing those who persecute you, contrasting with Job's defense against cursing.
Romans 12:14: Bless them which persecute you: bless, and curse not.
Contradiction with 1 Peter 3:9
Urges not to return evil for evil or insult for insult, but to bless instead, which presents a stronger perspective than simply not cursing in Job 31:30.
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
The verse might show a moral inconsistency because Job is discussing avoiding cursing or wishing harm on his enemy, which seems to conflict with other parts of the Bible that describe God or people seeking justice through punishment or harm to enemies. It raises questions about whether it's right or wrong to desire harm on someone who has wronged you.
