Yaakov 2:18-20 Orthodox Jewish Bible (OJB)
18 But someone will say, "You have emunah and I have ma’asim." You make known to me the Hisgalus haSod (the revelation of the mystery) of your emunah without your ma’asim, and I’ll show you, Chaver, from my ma’asim, the Emunah.
19 So you’re impressed with yourselves that with your emunah you can recite the kri’at Shema, nu? O you do so well...why, even the shedim have your da’as and emunah! But they shudder! [DEVARIM 6:4]
20 Are you willing to have da’as, O hollow man, that Emunah unharnessed to Ma’asim, stands idle?
