Psalm 140:3

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

They have venom like the venom of a serpent; Like a deaf cobra that stops up its ear,

Who have sharpened their tongue like a sword. They aimed bitter speech as their arrow,

The lips of those who rise against me and their whispering Are against me all day long.

“Their throat is an open tomb, With their tongues they keep deceiving,” “The poison of asps is under their lips”;

But no one can tame the tongue; it is a restless evil and full of deadly poison.
