Matthew 18:13-21
English Standard Version
Chapter 18
13And if he finds it, truly, I say to you, he rejoices over it more than over the ninety-nine that never went astray. 14So it is not the will of my Father who is in heaven that one of these little ones should perish.
15"If your brother sins against you, go and tell him his fault, between you and him alone. If he listens to you, you have gained your brother.
16But if he does not listen, take one or two others along with you, that every charge may be established by the evidence of two or three witnesses.
17If he refuses to listen to them, tell it to the church. And if he refuses to listen even to the church, let him be to you as a Gentile and a tax collector.
18Truly, I say to you, whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.
19Again I say to you, if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven.
20For where two or three are gathered in my name, there am I among them."
