Proverbs 17:15-28 (ESV)
15 He who justifies the wicked and he who condemns the righteous
are both alike an abomination to the Lord.
16 Why should a fool have money in his hand to buy wisdom
when he has no sense?
17 A friend loves at all times,
and a brother is born for adversity.
18 One who lacks sense gives a pledge
and puts up security in the presence of his neighbor.
19 Whoever loves transgression loves strife;
he who makes his door high seeks destruction.
20 A man of crooked heart does not discover good,
and one with a dishonest tongue falls into calamity.
21 He who sires a fool gets himself sorrow,
and the father of a fool has no joy.
22 A joyful heart is good medicine,
but a crushed spirit dries up the bones.
23 The wicked accepts a bribe in secret 
to pervert the ways of justice.
24 The discerning sets his face toward wisdom,
but the eyes of a fool are on the ends of the earth.
25 A foolish son is a grief to his father
and bitterness to her who bore him.
26 To impose a fine on a righteous man is not good,
nor to strike the noble for their uprightness.
27 Whoever restrains his words has knowledge,
and he who has a cool spirit is a man of understanding.
28 Even a fool who keeps silent is considered wise;
when he closes his lips, he is deemed intelligent.
