Mattityahu 18:17-19

Orthodox Jewish Bible

¹⁷ But if he refuses to listen to them, speak to the shtiebel kehillah, and if he even refuses to hear the kehillah, let him be to you as the Goy (heathen, pagan) and the moches (tax-collector).

¹⁸ Omein, I say to you, whatever you bind as asur (prohibited) on haaretz will have been bound in Shomayim, and whatever you permit as mutar on haaretz is mutar (permitted) in Shomayim.

¹⁹ Again, omein, I say to you, that if two of you will be in agreement about anything on haaretz that you petition for, it will be done for them by Avi shbaShomayim.
