Contradiction with Matthew 5:39
Jesus teaches to turn the other cheek, advocating non-retaliation, which contrasts with Solomon's command in 1 Kings 2:37, requiring Shimei to be put to death if he leaves Jerusalem, a retributive action.
Matthew 5:39: But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also.
Contradiction with Romans 12:17
Paul advises against repaying evil for evil, promoting peace, which opposes the death threat in 1 Kings 2:37 for Shimei if he crosses the brook Kidron.
Romans 12:17: Recompense to no man evil for evil. Provide things honest in the sight of all men.
Contradiction with Ezekiel 18:32
God expresses no pleasure in the death of anyone, urging repentance instead, contrary to the lethal restriction placed on Shimei in 1 Kings 2:37.
Ezekiel 18:32: For I have no pleasure in the death of him that dieth, saith the Lord GOD: wherefore turn [yourselves], and live ye. [yourselves: or, others]
Contradiction with James 2:13
James speaks about mercy triumphing over judgment, which conflicts with the strict and fatal judgment prescribed in 1 Kings 2:37 for leaving designated boundaries.
James 2:13: For he shall have judgment without mercy, that hath shewed no mercy; and mercy rejoiceth against judgment. [rejoiceth: or, glorieth]
