'Mischief' in the Bible

Behold, he travails with wickedness,And he conceives mischief and brings forth falsehood.

His mischief will return upon his own head,And his violence will descend upon his own pate.

His mouth is full of curses and deceit and oppression;Under his tongue is mischief and wickedness.

You have seen it, for You have beheld mischief and vexation to take it into Your hand.The unfortunate commits himself to You;You have been the helper of the orphan.

Day and night they go around her upon her walls,And iniquity and mischief are in her midst.

Can a throne of destruction be allied with You,One which devises mischief by decree?

“As for the head of those who surround me,May the mischief of their lips cover them.
