'Pen' in the Bible

For the choir director; according to the Shoshannim. A Maskil of the sons of Korah. A Song of Love.My heart overflows with a good theme;I address my verses to the King;My tongue is the pen of a ready writer.

“How can you say, ‘We are wise,And the law of the Lord is with us’?But behold, the lying pen of the scribesHas made it into a lie.
