Proverbs 11:9-12

An hypocrite with his mouth destroyeth his neighbour: But through knowledge shall the just be delivered. When it goeth well with the righteous, the city rejoiceth: And when the wicked perish, there is shouting. By the blessing of the upright the city is exalted: But it is overthrown by the mouth of the wicked. He that is void of wisdom despiseth his neighbour: But a man of understanding holdeth his peace.
