Proverbs 17:28
Even a fool who keeps silent is considered wise;
when he closes his lips, he is deemed intelligent.
The point of this proverb and the previous one is that the best use of words comes from a measured restraint, or to use a common phrase – think before you speak. The problem with the fool is that he speaks quickly without considering his words. He speaks on impulse. He does not consider how others perceive him as he is speaking.
Think through what to say and how to say it. And if you can’t think of what to say, then be silent. You will be considered wise until you prove otherwise. Indeed, your silence can be a very tool for communicating that you have something to say. It is better to have others cajole you into sharing your thoughts, than for you to impose them on reluctant hearers. Words that are not readily given become more sought after than the words spilled out quickly.
