Proverbs 23:1 says, When thou sittest to eat with a ruler, consider diligently what is before thee:  If we find ourselves eating with a ruler, we are to think about how much we are eating and not just give in to gluttony when given a chance to eat anything we desire.  Matthew Henry applies this to the Lord's Supper especially, which at one time was evidently more of a feast than what observe today.  Verse two adds, And put a knife to thy throat, if thou be a man given to appetite.  Not controlling our appetites and desires is so bad that we would be better off putting a knife to our throat than giving in to them.  God expects us to be guided by the Holy Spirit in all that we do, and when we are, we will live in moderation in all things.  Verse three states, Be not desirous of his dainties: for they are deceitful meat.  This is still referring to eating, and the warning is that not everything that looks good is actually healthy.  The same can be said of anything that tempts us.  Just because something looks appealing doesn't mean that it is good for us.  Verse four says, Labour not to be rich: cease from thine own wisdom.   We may think this is the opposite of what we are taught.  We work to become more wealthy in today's society, but the warning I believe is that we should work to bring honor to God and to help others first.  We are not to live by our own understanding, but by the understanding of God.  Verse five asks, Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.  We are asked if we will live chasing the riches of the world, which are but temporary at best.  We should live for the glory of and under the guidance of God.  Verse six declares, Eat thou not the bread of him that hath an evil eye, neither desire thou his dainty meats:  This is a warning about associating too much with those who gain their riches through evil methods.  We are not to desire to be like them, even if they are rich in the eyes of the world.  Verse seven adds, For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.  Even as an evil person invites us to eat with them, they really have no concern for us.  Verse eight adds, The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.  Eating things that are gained through evil actions should make us sick, as should sweet words that are said with no real meaning.  Verse nine states, Speak not in the ears of a fool: for he will despise the wisdom of thy words.  The fool, the person who rejects God, will despise us when we speak the truth of God.  Verse ten declares, Remove not the old landmark; and enter not into the fields of the fatherless:  This is another warning about attempting to cheat others, especially those who are really less fortunate.  We are not to change the old landmarks to claim more than we are entitled to, and we are especially not to take advantage of those who are fatherless.  Verse eleven adds, For their redeemer is mighty; he shall plead their cause with thee.   We may think we can get away with abusing the poor and the fatherless, but God is with them as their advocate.  This does not mean that all who are poor and fatherless will be saved, but God will always work to protect them.  God always calls on His own to help the poor.  Verse twelve proclaims, Apply thine heart unto instruction, and thine ears to the words of knowledge.  Instead of chasing after the riches and wisdom of the world, we are to follow the instructions and leadership of God.  This is the only way to true understanding.  Verse thirteen says, Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.  This is not politically correct advise, but it is better to discipline a child, even with physical punishment, than to let them do whatevseeer they want.  Verse fourteen adds, Thou shalt beat him with the rod, and shalt deliver his soul from hell.  I don't believe either of these two verses means that we are to punish a child by excessive physical punishment, but the we should do all that we can to teach them to live in obedience to the law, especially God's law.  The key is following God's guidance as we discipline our children.  Verse fifteen states, My son, if thine heart be wise, my heart shall rejoice, even mine.  We can apply this to an earthly father rejoicing when a child lives by the wisdom of God, but it even more so applies to God rejoicing when His children act with wisdom.  Verse sixteen says, Yea, my reins shall rejoice, when thy lips speak right things.  I believe this means that God will rejoice when we follow His reins, or guidance, and speak His word to the world.  Verse seventeen declares, Let not thine heart envy sinners: but be thou in the fear of the LORD all the day long.  We may look at those who are rich with envy, but we are warned not to envy those who have gotten their riches through evil.  Verse eighteen states, For surely there is an end; and thine expectation shall not be cut off.  There will always be an end to the things gained in these two world.  When we follow God's guidance, our expectations will never fail us.
