Yochanan I 2:18-21

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.
