What does Proverbs 24:4 mean?

Evil people want to destroy lives (Proverbs 24:1), as their plans often involve taking advantage of others. Immorality leads to ruin in eternity (Proverbs 10:29; 18:7) and often brings harsh consequences in this life (Proverbs 8:32–36). In contrast, those who seek knowledge (Proverbs 1:7; 2:1–6) build others up; they gain valuable understanding (Proverbs 8:10; 23:23) which helps them succeed. Earlier sections of this book depicted foolishness as leading to the ruin of a house (Proverbs 2:16–19; 14:1, 11). Here, one's house—a literal home or any other effort—is enhanced by the application of wisdom.

It is not out of the question to parallel the "precious and pleasant riches" of this verse with the beautiful, valuable characteristics mentioned in Galatians 5:22–23 and in 2 Peter 1:5–7. It is wise to be controlled by the Holy Spirit, because He furnishes our lives with the fruit mentioned in Galatians 5:22–23: "love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self-control." The apostle Peter exhorts believers to add to their faith by furnishing their lives with the following valuable qualities: virtue, knowledge, self-control, steadfastness, godliness, brotherly affection, and love (2 Peter 1:5–7). Such things are worthwhile in and of themselves; they also bring great benefits to those who apply them.
