¹⁵ “If your brother or sister^[a] sins,^[b] go and point out their fault, just between the two of you. If they listen to you, you have won them over. ¹⁶ But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’^[c] 17 If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.

¹⁸ “Truly I tell you, whatever you bind on earth will be^[d] bound in heaven, and whatever you loose on earth will be^[e] loosed in heaven.

¹⁹ “Again, truly I tell you that if two of you on earth agree about anything they ask for, it will be done for them by my Father in heaven. ²⁰ For where two or three gather in my name, there am I with them.”
