אֵיכָ֤ה תֹֽאמְרוּ֙ חֲכָמִ֣ים אֲנַ֔חְנוּ וְתוֹרַ֥ת יְהוָ֖ה אִתָּ֑נוּ אָכֵן֙ הִנֵּ֣ה לַשֶּׁ֣קֶר עָשָׂ֔ה עֵ֖ט שֶׁ֥קֶר סֹפְרִֽים׃
How do ye say: ‘We are wise, and the Law of the LORD is with us’? Lo, certainly in vain hath wrought the vain pen of the scribes.
Rashi on Jeremiah
Verily, behold it is in vain Behold your wisdom is in vain within you to heal you lightly.
