Proverbs 28:15 says, As a roaring lion, and a ranging bear; so is a wicked ruler over the poor people.  A wicked ruler is just as dangerous to those that they rule over as a roaring lion or a ranging bear.  Verse sixteen states, The prince that wanteth understanding is also a great oppressor: but he that hateth covetousness shall prolong his days.  Wanteth means lacking understanding.  Rulers who lack understanding will allow their coveteousness to influence their decisions.  They will do what is best for them and not what is best for those that they rule over.  Verse seventeen declares, A man that doeth violence to the blood of any person shall flee to the pit; let no man stay him.  This is a warning against murdering someone.  A murderer should pay for murdering someone, and we are not to help someone who commits murder get away with it.  Verse eighteen proclaims, Whoso walketh uprightly shall be saved: but he that is perverse in his ways shall fall at once.  We could interpret this to mean that we can be saved by our own goodness, or walking uprightly, but I believe that it means walking under the leadership of the Holy Spirit.  If we do not accept Christ and follow God's guidance, we will certainly fall when judgment comes.  Verse nineteen says, He that tilleth his land shall have plenty of bread: but he that followeth after vain persons shall have poverty enough.  We are to do honest work if we are to have enough bread to eat.  Following after the get rich schemes of others will only lead to our poverty.  Verse twenty states,  A faithful man shall abound with blessings: but he that maketh haste to be rich shall not be innocent.  I believe that this is simply another way of saying that we should be honest in our dealings with others.  If we are, we will abound in the blessings of God.  Verse twenty-one declares,  To have respect of persons is not good: for for a piece of bread that man will transgress.  We are to treat all people with fairness, no matter who they may be.  Our judgment or treatment of others should never be able to be bought.  Verse twenty-two states, He that hasteth to be rich hath an evil eye, and considereth not that poverty shall come upon him.  This is another warning against get rich quick schemes, no matter how appealing they may seem.  Some people will seemingly do anything to get rich, and those riches will always be but temporary.  Verse twenty-three says, He that rebuketh a man afterwards shall find more favour than he that flattereth with the tongue.  It is better for us to rebuke someone who is guilty of sin than it is for us to flatter them.   Even if people are rich and powerful that does not mean that we are to always to speak of them with admiration.  Of course, this applies to all people, no matter their status in life, but we tend to flatter the rich more than the poor.  Verse twenty-four warns, Whoso robbeth his father or his mother, and saith, It is no transgression; the same is the companion of a destroyer.  We cannot just take what belongs to our parents without their permission and claim that it is okay.  We hear too often about people stealing from or even abusing their parents, and this is never acceptable.  Verse twenty-five declares, He that is of a proud heart stirreth up strife: but he that putteth his trust in the LORD shall be made fat.  Self-pride leads people to stir up strife, or create problems for those around them.  Those filled with self pride care only about what is best for them.  When we put our faith in God, we will be made fat spiritually, even if we are poor in the eyes of the world.  Verse twenty-six proclaims, He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.  If we are to walk with wisdom, we must follow God's leadership at all times.  If we attempt to rely on our own heart, or understanding, we will never prosper spiritually.  Verse twenty-seven says, He that giveth unto the poor shall not lack: but he that hideth his eyes shall have many a curse.  Once more, we as followers of Christ are called on to help the poor.  We are never to just overlook them and pretend they don't exist.  Verse twenty-eight states, When the wicked rise, men hide themselves: but when they perish, the righteous increase.  If wicked people are in power, those who follow God may be in danger.  In some parts of the world today, it is dangerous to openly declare oneself to be a Christian.  If these people fall out of power, then it is easier for those who follow God to prosper.  I cannot say when it is right for a Christian to hide their faith, but I am certain that God will let us know.
