Proverbs 24:2
King James Version
“For their heart studieth destruction, and their lips talk of mischief.”
Context
1Be not thou envious against evil men, neither desire to be with them.
2For their heart studieth destruction, and their lips talk of mischief.
3Through wisdom is an house builded; and by understanding it is established:
4And by knowledge shall the chambers be filled with all precious and pleasant riches.
5A wise man strong; yea, a man of knowledge increaseth strength.
