1 John 2:18-23 English Standard Version (ESV)
Warning Concerning Antichrists
18 Children, it is the last hour, and as you have heard that antichrist is coming, so now many antichrists have come. Therefore we know that it is the last hour. 19 They went out from us, but they were not of us; for if they had been of us, they would have continued with us. But they went out, that it might become plain that they all are not of us. 20 But you have been anointed by the Holy One, and you all have knowledge.[a] 21 I write to you, not because you do not know the truth, but because you know it, and because no lie is of the truth. 22 Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. 23 No one who denies the Son has the Father. Whoever confesses the Son has the Father also.
Yochanan I 2:18-23 Orthodox Jewish Bible (OJB)
18 Yeladim, it is the sha’ah ha’achronah (the last hour, time), and as you heard that Anti-Moshiach is coming, even now many Anti-Moshiachs [nevi’ei sheker, 4:1] have come, from which we have da’as that it is the sha’ah ha’achronah.
19 They went out and departed from us, but they were not of us; for if they were of us, they would have abided with us; but they went out that it may be niglah (be revealed) that none of them belongs to us. [Yn 6:70; 13:30]
20 And you have a [Ruach Hakodesh] mishcha (anointing) from HaKadosh and you have da’as of all. [YIRMEYAH 31:34]
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.
