Yirmeyah 17:8-10

Orthodox Jewish Bible

⁸ For he shall be as an etz planted by the mayim, and that spreadeth out her shorashim (roots) by the brook, and shall not fear when chom (heat) cometh, but its leaf shall be green; and shall not be anxious in the shenat batzoret (year of drought), neither shall cease from yielding p’ri (fruit).

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.
