Matthew 18:15-20 New King James Version (NKJV)

Dealing with a Sinning Brother

¹⁵ “Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. ¹⁶ But if he will not hear, take with you one or two more, that ‘by the mouth of two or three witnesses every word may be established.’ ¹⁷ And if he refuses to hear them, tell it to the church. But if he refuses even to hear the church, let him be to you like a heathen and a tax collector.

¹⁸ “Assuredly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.

¹⁹ “Again^[a] I say to you that if two of you agree on earth concerning anything that they ask, it will be done for them by My Father in heaven. ²⁰ For where two or three are gathered together in My name, I am there in the midst of them.”
