Four Great Sins

Proverbs 17:4-5

A wicked person listens to deceitful lips;
 a liar pays attention to a destructive tongue.
Whoever mocks the poor  shows contempt for their Maker;
 whoever gloats over disaster  will not go unpunished.
Two abominations to God

Proverbs 17:15

Acquitting the guilty and condemning the innocent —
 the Lord detests them both.
Why some remain fools

Proverbs 17:16

Why should fools have money in hand to buy wisdom,
 when they are not able to understand it?
How to know true friends

Proverbs 17:17

A friend loves at all times,
 and a brother is born for a time of adversity.
Seven things that cause sorrow

Proverbs 17:18-21

One who has no sense shakes hands in pledge
 and puts up security for a neighbour.
    Whoever loves a quarrel loves sin;
 whoever builds a high gate invites destruction.
    One whose heart is corrupt does not prosper;
 one whose tongue is perverse falls into trouble.
    To have a fool for a child brings grief;
 there is no joy for the parent of a godless fool.
