'Mischievous' in the Bible

For they planned evil against You;They devised a [malevolent] plotAnd they will not succeed.

Those who seek my life lay snares for me,And those who seek to injure me threaten mischievous things and destruction;They devise treachery 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].
