Psalm 10:7

His (the wicked man's) mouth is full of lies and threats; trouble and evil are under his tongue.

His mouth is full 
Romans 3:14  "Their mouths are full of cursing and bitterness."

of lies and threats 
Psalm 73:8  They scoff, and speak with malice; with arrogance they threaten oppression.
Psalm 119:134  Redeem me from human oppression, that I may obey your precepts.
Ecclesiastes 4:1  Again I looked and saw all the oppression that was taking place under the sun: I saw the tears of the oppressed--and they have no comforter; power was on the side of their oppressors--and they have no comforter.
Isaiah 30:12-13  Therefore this is what the Holy One of Israel says: "Because you have rejected this message, relied on oppression and depended on deceit, this sin will become for you like a high wall, cracked and bulging, that collapses suddenly, in an instant."

trouble and evil are under his tongue 
Job 20:12-14  "Though evil is sweet in his mouth and he hides it under his tongue, though he cannot bear to let it go and lets it linger in his mouth, yet his food will turn sour in his stomach; it will become the venom of serpents within him."
