Speak Softly (and Your Tongue will Turn into a Tree, or Something)
Speaking softly helps calm the wrath of other people, and if your tongue is gentle, it's "a tree of life."
God watches over everything, says the author, measuring it all up.
Fools don't listen to their parents, and end up having money problems. Their sacrifices don't please God—but the prayers of the righteous do.
Yet again—rebukes are good for you. Deal with it, says the author.
God can see into all human hearts, in addition to the underworld.
Gladness of heart is good, sadness is bad (this is maybe another proverb for the "obvious" file).
Cheerfulness is like a continual feast—you create your own enjoyment.
It's better not to have too much and still fear God than to be overloaded with treasure and trouble. Similarly it's better to have love and eat a simple meal of vegetables than to eat a meaty feast while in a mood of hatred.
The Usual Culprits
Again, the writer attacks familiar targets: a quick temper, laziness, evil plans, foolish children, greed, a lack of wise advisors. Conversely, he-she praises their opposites.
In line with the general policy of repeating stuff, the book again notes how righteousness and wisdom lead upward away from Sheol (the underworld).
Righteous people think before they speak, while the wicked just blabber out evil things.
The "light of the eyes" (probably witnessing good things—or else something like Cyclops from X-Men) refreshes the heart, and good news brings life back to the body.
The author repeats that one should listen to instruction and that fearing God is the beginning of wisdom.
