Proverbs 23 (KJV)

4 Labour not to be rich: cease from thine own wisdom.

9 Speak not in the ears of a fool: for he will despise the wisdom of thy words.

12 Apply thine heart unto instruction, and thine ears to the words of knowledge.

13 Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.
14 Thou shalt beat him with the rod, and shalt deliver his soul from hell.

17 Let not thine heart envy sinners: but be thou in the fear of the Lord all the day long.

23 Buy the truth, and sell it not; also wisdom, and instruction, and understanding.
