Yochanan I 2:21-23 Orthodox Jewish Bible (OJB)
21 I did not write an iggeret kodesh to you because you do not have da’as of HaEmes, but because you do have da’as of HaEmes and that kol sheker (every falsehood) is not of HaEmes.
22 Who is the shakran (liar)? Who but the one making hakhchashah (denial) and claiming that Yehoshua is not the Rebbe, Melech HaMoshiach? This one is the Anti-Moshiach, the one making hakhchashah (denial) of HaAv and HaBen.
23 No one making hakhchashah of HaBen has HaAv; the one making hoda’ah (confession) of HaBen has HaAv also.
