Yirmeyah 17:9-11

Orthodox Jewish Bible

⁹ The lev (heart, mind) akov (is deceitful) above all things, and anush (incurable [in wickedness]); who can know it?

¹⁰ I, Hashem, search the lev, I test the kelayot (kidneys, i.e., most inward parts), requiting to every ish according to his drakhim, and according to the p’ri of his deeds.

¹¹ As the partridge sitteth on eggs, and hatcheth them not; so he that getteth osher (riches), and not by mishpat, shall leave them in the midst of his days, and at his end shall be a naval (fool).
