Contradiction with Matthew 5:39
Proverbs 25:23 advocates for the north wind driving away rain and an angry countenance driving away a backbiting tongue, suggesting a response to offense, whereas Matthew 5:39 advises turning the other cheek instead of retaliating when wronged.
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.
