'Mischievous' in the Bible

For they intended evil against thee: they imagined a mischievous device, which they are not able to perform.

They also that seek after my life lay snares for me: and they that seek my hurt speak mischievous things, and imagine deceits all the day long.

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

The beginning of the words of his mouth is foolishness: and the end of his talk is mischievous madness.

That they may do evil with both hands earnestly, the prince asketh, and the judge asketh for a reward; and the great man, he uttereth his mischievous desire: so they wrap it up.
