'Mischievous' in the Bible

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

Rest in Jehovah, and wait patiently for him: fret not thyself because of him that prospereth in his way, because of the man that bringeth mischievous devices to pass.

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.

And when one comes to see me, he speaks empty words,While his heart gathers malicious gossip [against me];When he goes away, he tells it [everywhere].

Thy tongue deviseth mischievous things, like a sharp razor, practising deceit.
