Matthew 18
15 Ref And if your brother does wrong to you, go, make clear to him his error between you and him in private: if he gives ear to you, you have got your brother back again.
16 Ref But if he will not give ear to you, take with you one or two more, that by the lips of two or three witnesses every word may be made certain.
17 Ref And if he will not give ear to them, let it come to the hearing of the church: and if he will not give ear to the church, let him be to you as a Gentile and a tax-farmer.
18 Ref Truly I say to you, Whatever things are fixed by you on earth will be fixed in heaven: and whatever you make free on earth will be made free in heaven.
