In these first few verses it's talking about trusting in God's wisdom and not trying to use your own. If you trust in God's wisdom your life will be long and happy.
(9-18) Honour the Lord with thy substance, and with the firstfruits of all thine increase: So shall thy barns be filled with plenty, and thy presses shall burst out with new wine. My son, despise not the chastening of the Lord; neither be weary of his correction: For whom the Lord loveth he correcteth; even as a father the son in whom he delighteth. Happy is the man that findeth wisdom, and the man that getteth understanding. For the merchandise of it is better than the merchandise of silver, and the gain thereof than fine gold. She is more precious than rubies: and all the things thou canst desire are not to be compared unto her. Length of days is in her right hand; and in her left hand riches and honour. Her ways are ways of pleasantness, and all her paths are peace. She is a tree of life to them that lay hold upon her: and happy is every one that retaineth her.
In these next verses it talks about all the things you can gain by following the wisdom of God. It talks about how you will once again be happy and have long life. It also talks about how you will be prosperous. It makes a lot of sense because if you live your life with wisdom and arm yourself with knowldge you will be able to make good decisions leading you to these things.
(19-26) The Lord by wisdom hath founded the earth; by understanding hath he established the heavens. By his knowledge the depths are broken up, and the clouds drop down the dew. My son, let not them depart from thine eyes: keep sound wisdom and discretion: So shall they be life unto thy soul, and grace to thy neck. Then shalt thou walk in thy way safely, and thy foot shall not stumble. When thou liest down, thou shalt not be afraid: yea, thou shalt lie down, and thy sleep shall be sweet. Be not afraid of sudden fear, neither of the desolation of the wicked, when it cometh. For the Lord shall be thy confidence, and shall keep thy foot from being taken.
This talks about how God used wisdom and knowldge to create the heavens and the earth. We see this all the time through how intricately everything works together. Ecosystems, the human body, weather, the solar system, etc. We should strive to be like God in all ways possible and one of those ways is by gaining wisdom and intelligence. It also talks about how wisdom and knowledge can give you security so that you don't have to fear for things.
(27-35) Withhold not good from them to whom it is due, when it is in the power of thine hand to do it. Say not unto thy neighbour, Go, and come again, and to morrow I will give; when thou hast it by thee. Devise not evil against thy neighbour, seeing he dwelleth securely by thee. Strive not with a man without cause, if he have done thee no harm. Envy thou not the oppressor, and choose none of his ways. For the froward is abomination to the Lord: but his secret is with the righteous. The curse of the Lord is in the house of the wicked: but he blesseth the habitation of the just. Surely he scorneth the scorners: but he giveth grace unto the lowly. The wise shall inherit glory: but shame shall be the promotion of fools
This talks about not being stingy with the things you have. It says if someone deserves something you shouldn't hold it back when you have the ability to do it. When someone needs something and you have it, you shouldn't tell them to go away and come another time if you have it. Don't spread evil/falsehoods about someone simply because you are jealous of what they have. Don't fight with someone if they have never done anything to you to cause it. Don't look up to violent, evil people and don't try and imitate them. God will bless those who follow wisdom, not fools.
