Proverbs 24:3 (KJV)

Be not thou envious against evil men, neither desire to be with them.

For their heart studieth destruction, and their lips talk of mischief.

And by knowledge shall the chambers be filled with all precious and pleasant riches.

A wise man is strong; yea, a man of knowledge increaseth strength.

For by wise counsel thou shalt make thy war: and in multitude of counsellors there is safety.

Wisdom is too high for a fool: he openeth not his mouth in the gate.

He that deviseth to do evil shall be called a mischievous person.
