Kehillah in Galatia 1:8-10

Orthodox Jewish Bible

⁸ But even if we [Shlichim, emissaries of Rebbe, Melech HaMoshiach] or a malach from Shomayim should pose as maggidim [for Moshiach] and make a hachrazah (proclamation) to you of a "Besuras HaGeulah" other than that Besuras HaGeulah which we preached to you, let such a one be ARUR HAISH ("Cursed is the man," YEHOSHUA 6:26) and set under cherem (ban of destruction) and onesh Gehinnom (damnation).

⁹ As we have previously said, and now again I say, if any one preaches a "Besuras HaGeulah" to you other than that which you received, let him be ARUR HAISH and be consigned to onesh Gehinnom.

¹⁰ Am I now seeking the ishshur (approval) of Bnei Adam? Or the haskama (approval) of Hashem? Or am I seeking to be a man-pleaser? If (and this is not the case) I were still pleasing Bnei Adam, I would not have been the eved of Moshiach.
