The chapter begins with a call not to forget the father's teaching and to keep his commands in the heart, because they will bring length of days and peace. The son is to bind steadfast love and faithfulness around his neck, and so he will find favor and a good name with God and people (vv. 1-4).
Then come the best-known verses: trust in the Lord with all your heart, do not lean on your own understanding, acknowledge him in all your ways, and do not be wise in your own eyes but fear the Lord and turn from evil (vv. 5-8). The son is to honor the Lord with his wealth and with the firstfruits of his crops, and he is promised that his barns will be filled (vv. 9-10). He must also accept the Lord's discipline, because the Lord reproves the one he loves, as a father the son in whom he delights (vv. 11-12).
Verses 13 to 20 praise wisdom: she is better than silver and gold, more precious than jewels, and a tree of life to those who grasp her. By wisdom the Lord founded the earth and established the heavens. The father then returns to exhortations: keep sound judgment and discretion, and so sleep without fear and without dread of sudden calamity (vv. 21-26).
Verses 27 to 35 deal with the neighbor. Do not withhold good from those who deserve it when it is in your power to give, do not tell a neighbor to come back tomorrow, do not plot harm against one who lives trustingly beside you, do not quarrel without cause and do not envy a violent man. The Lord curses the house of the wicked and blesses the dwelling of the righteous; he scoffs at scoffers and gives favor to the humble. The wise will inherit honor, but fools will get disgrace.
