9If a wise man contendeth with a foolish man, whether he rage or laugh, there is no rest. 10The bloodthirsty hate the upright: but the just seek his soul. 11A fool uttereth all his mind: but a wise man keepeth it in till afterwards. 12If a ruler hearken to lies, all his servants are wicked. 13The poor and the deceitful man meet together: the LORD lighteneth both their eyes.
