'Deceitful' in the Bible

For they speak not peace; and they devise deceitful words against the quiet in the land.

Judge me, O God, and plead my cause against an ungodly nation; deliver me from the deceitful and unrighteous man.

Thou hast loved all devouring words, O deceitful tongue!

And thou, O God, wilt bring them down into the pit of destruction: bloody and deceitful men shall not live out half their days. But as for me, I will confide in thee.

And they drew back and dealt treacherously like their fathers: they turned like a deceitful bow.

Jehovah, deliver my soul from the lying lip, from the deceitful tongue.

What shall be given unto thee, what shall be added unto thee, thou deceitful tongue?
