Proverbs 1:5

Proverbs 1:5
​"A wise [man] will hear, and will increase learning; and a man of understanding shall attain unto wise counsels:"
Be quick to listen and slow to speak is a very good way of learning. A man of understanding will want to be counseled by older, wiser men. They will be quick to be instructed by someone who has already experienced the same thing. These wise counsels can save many mistakes.
The wise believer will have the ability to guide or govern others with truth.
