Yaakov 4:15-17

Orthodox Jewish Bible

¹⁵ Instead of this, you ought to say "Im yirtzeh Hashem" ("if the L-rd wills") "we will live, also we will do this or that."

¹⁶ But now you boast in your pretensions. All such ravrevanut (boastfulness) is ra’ah (evil, wickedness).

¹⁷ To the one having da’as, therefore, knowing to do tov and not doing it, to him it is chet.
