'Pen' in the Bible

{To the chief Musician. Upon Shoshannim. Of the sons of Korah. An instruction; a song of the Beloved.} My heart is welling forth with a good matter: I say what I have composed touching the king. My tongue is the pen of a ready writer.

How do ye say, We are wise, and the law of Jehovah is with us? Behold, certainly the lying pen of the scribes hath made it falsehood.
