Proverbs 23:12 (KJV)

For as he thinketh in his heart, so is he: Eat and drink, saith he to thee; but his heart is not with thee.

The morsel which thou hast eaten shalt thou vomit up, and lose thy sweet words.

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

Remove not the old landmark; and enter not into the fields of the fatherless:

For their redeemer is mighty; he shall plead their cause with thee.

Withhold not correction from the child: for if thou beatest him with the rod, he shall not die.

Thou shalt beat him with the rod, and shalt deliver his soul from hell.

My son, if thine heart be wise, my heart shall rejoice, even mine.

Yea, my reins shall rejoice, when thy lips speak right things.

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