LETTER TO MA'AMINIM YEHUDIM 3

12 Beware, Achim b’Moshiach, lest there will be in any one of you a lev rah (evil heart) without Emunah, that turns away shmad from Elohim Chayyim. 13 Instead, give one another chozek (strength) each and every day, as long as it is still called "HAYOM," (today)*3:13 Ps 95:7 lest some of you may fall into KESHI (stubbornness, hardness)*3:13 Dt 9:27 and be stubbornly hardened by the nechalim (deceitfulness) of Chet.
