Kohelet 12:9-11

Orthodox Jewish Bible

⁹ And moreover, because Kohelet was chacham, he taught the people da’as; yea, he applied, and searched out, and set in order many meshalim (proverbs).

¹⁰ Kohelet searched to find out divrei chefetz; and that which was written was yosher, even divrei emes.

¹¹ Divrei chachamim are like goads, and like nails firmly fixed are the collected sayings that are given by Ro’eh Echad (One Shepherd).
