'Words of the Wise' in the Bible

To understand a proverb, and the interpretation; the words of the wise, and their dark sayings.

Speaking recklessly is like the thrusts of a sword, but the words of the wise bring healing.

What a fool says brings a rod to his back, but the words of the wise protect them.

Bow down thine ear, and hear the words of the wise, and apply thine heart unto my knowledge.
