Contradiction with 1 Samuel 16:7
This verse emphasizes that God values the heart over outward appearances, which contradicts the emphasis on rank and honor based on feats of valor in 2 Samuel 23:19.
1 Samuel 16:7: But the LORD said unto Samuel, Look not on his countenance, or on the height of his stature; because I have refused him: for [the LORD seeth] not as man seeth; for man looketh on the outward appearance, but the LORD looketh on the heart. [outward...: Heb. eyes]
Contradiction with Matthew 20:16
This verse states that the last shall be first and the first last, which contradicts the principle of ranking men by their achievements as depicted in 2 Samuel 23:19.
Matthew 20:16: So the last shall be first, and the first last: for many be called, but few chosen.
Contradiction with Luke 22:26
This verse teaches that the greatest among you should be like the youngest and the leader like the one who serves, opposing the hierarchical ranking seen in 2 Samuel 23:19.
Luke 22:26: But ye [shall] not [be] so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve.
