Verses 1-28
Selfish ambition (28:1-28)
A bad conscience makes a person a coward, but a clear conscience gives a person courage (28:1). Some characteristics of a corrupt society are instability in the government, exploitation of fellow citizens (even among the poorer classes), lawlessness, reversal of moral standards, injustice and greed. In spite of this, some will always remain true to God (2-7).
Even those who are religious may be guilty of exploiting the poor and misleading the upright, but their religious exercises will not help them escape God's judgment. Those who are poor yet godly see this truth and believe that one day they will prosper, whereas their oppressors will suffer (8-12). Hidden sins and a hardened conscience alike bring God's judgment (13-14).
Although an individual may suffer a lifetime for causing the death of another, a whole nation may suffer because of the fury and ignorance of a despotic ruler (15-17). Those who live and work honestly need not fear the future (18-19), but those who are greedy will in the end be driven into poverty. Some are so greedy they can be bribed even by a piece of bread (20-22)!
No one should neglect these warnings, for a sincere rebuke is better than flattery (23). In their greed for riches, people at times cheat their parents, stir up trouble, become self-centred, neglect the poor and ignore injustice. But those who live only for themselves will one day suffer as they have made others suffer (24-28).
