Proverbs 24:2

His mouth is full of cursing and deceit and fraud: under his tongue is mischief and vanity.

Behold, he travaileth with iniquity, and hath conceived mischief, and brought forth falsehood.

Draw me not away with the wicked, and with the workers of iniquity, which speak peace to their neighbours, but mischief is in their hearts.

None calleth for justice, nor any pleadeth for truth: they trust in vanity, and speak lies; they conceive mischief, and bring forth iniquity.

They conceive mischief, and bring forth vanity, and their belly prepareth deceit.

And David knew that Saul secretly practised mischief against him; and he said to Abiathar the priest, Bring hither the ephod.

And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord?

Then assembled together the chief priests, and the scribes, and the elders of the people, unto the palace of the high priest, who was called Caiaphas, And consulted that they might take Jesus by subtilty, and kill him.

And he thought scorn to lay hands on Mordecai alone; for they had shewed him the people of Mordecai: wherefore Haman sought to destroy all the Jews that were throughout the whole kingdom of Ahasuerus, even the people of Mordecai. In the first month, that is, the month Nisan, in the twelfth year of king Ahasuerus, they cast Pur, that is, the lot, before Haman from day to day, and from month to month, to the twelfth month, that is, the month Adar.

Pilate therefore, willing to release Jesus, spake again to them. But they cried, saying, Crucify him, crucify him.

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.

Frowardness is in his heart, he deviseth mischief continually; he soweth discord.

Which imagine mischiefs in their heart; continually are they gathered together for war.

He deviseth mischief upon his bed; he setteth himself in a way that is not good; he abhorreth not evil.

That they may shoot in secret at the perfect: suddenly do they shoot at him, and fear not. They encourage themselves in an evil matter: they commune of laying snares privily; they say, Who shall see them? They search out iniquities; they accomplish a diligent search: both the inward thought of every one of them, and the heart, is deep.

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