Some people think words do not cause harm. Scripture offers a different perspective. Words hold the power of "life and death" (Proverbs 18:21).
Proverbs lists many things we say that cause harm:
lies (Proverbs 14:5, 25)
arguments (Proverbs 26:17)
insults or curses (Proverbs 20:20)
speaking falsely about someone to damage their reputation (Proverbs 10:18)
spreading private information about others or unverified stories passed from person to person (Proverbs 11:13; 18:8)
excessive or insincere praise given to manipulate someone (Proverbs 7:21–22)
speaking too proudly about oneself (Proverbs 26:23; 27:2)
The book of Proverbs often emphasizes that foolish people say foolish things. “The woman named Folly” symbolizes these people (9:13–18). She lies and deceives to harm her listeners. Words show the heart's condition (16:23; 18:4).
Someone might hide an evil heart with pleasant words (26:23). But true character will eventually appear (26:24–26). Foolish words harm others and eventually hurt the speaker. The tongue is full of wickedness that can ruin your life (James 3:6).
In contrast, wise people speak words that give life, as shown by wisdom (Proverbs 8:7–9; 10:11). Wise people use their words carefully and are usually gentle (17:27–28; 15:4; 16:24). Yet, a wise person also knows the right time to speak (15:23; 25:11). This person understands that sometimes even harsh criticism is necessary (see 27:5). The book of Proverbs wisely reminds readers to pay attention not only to what they say but also to how and when they say it.
