10 Bloodthirsty men hate one who is blameless
and seek the life of the upright. 
11 A fool gives full vent to his spirit,
but a wise man quietly holds it back.
12 If a ruler listens to falsehood,
all his officials will be wicked.
13 The poor man and the oppressor meet together;
the Lord gives light to the eyes of both.
14 If a king faithfully judges the poor,
his throne will be established forever.
15 The rod and reproof give wisdom,
but a child left to himself brings shame to his mother.
16 When the wicked increase, transgression increases,
but the righteous will look upon their downfall.
17 Discipline your son, and he will give you rest;
he will give delight to your heart. (ESV)
 29:10 Or but the upright seek his soul
Iron sharpens iron,
and one man sharpens another.
