לֹא־נָאוָ֣ה לְנָבָ֣ל שְׂפַת־יֶ֑תֶר אַ֝֗ף כִּֽי־לְנָדִ֥יב שְׂפַת־שָֽׁקֶר׃
דעם מנוּװל פּאַסט ניט די שפּראַך פֿון ברײטקײט, נאָך װינציקער דעם נַדבֿן די שפּראַך פֿון ליגן.

And so there is no superfluous talk, (Proverbs 17:7) nor anything that is extraneous, remote or forced in the book. Its order and composition, its style and insights, are the mark and proof that it embodies God's wisdom and was written with inspiration from on High by that person [Moses] like whom there has been no other in Israel. (Deuteronomy 34:10.)
