Mattityahu 18:15-17

Orthodox Jewish Bible

¹⁵ And if your Ach b’Moshiach sins against you, go and reprove him in private, just between the two of you; if he listens to you, you have gained your Ach b’Moshiach.

¹⁶ But if he does not listen to you, take one or two more Achim b’Moshiach with you, so that by the PI SHNAYIM SHLOSHAH EDIM (by the mouth of two or three witnesses, DEVARIM 19:15) every word shall be established.

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).
