'Treacherous' in the Bible

Also let none waiting on Thee be ashamed, Let the treacherous dealers without cause be ashamed.

You love any words that destroy,you treacherous tongue!

And Thou, Jehovah, God of Hosts, God of Israel, Awake to inspect all the nations. Favour not any treacherous dealers of iniquity. Selah.

But turned back and acted treacherously like their fathers;They turned aside like a treacherous bow.

I watch the treacherous, and despise them, because they do not do what you have said.

What will be given to you, and what will be done to you, you treacherous tongue?
