Matthew 18:15-20 World English Bible (WEB)
15 “If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother. 16 But if he doesn’t listen, take one or two more with you, that at the mouth of two or three witnesses every word may be established.[a] 17 If he refuses to listen to them, tell it to the assembly. If he refuses to hear the assembly also, let him be to you as a Gentile or a tax collector. 18 Most certainly I tell you, whatever things you bind on earth will have been bound in heaven, and whatever things you release on earth will have been released in heaven. 19 Again, assuredly I tell you, that if two of you will agree on earth concerning anything that they will ask, it will be done for them by my Father who is in heaven. 20 For where two or three are gathered together in my name, there I am in the middle of them.”
Matthew 18:15-20 New International Version (NIV)
Dealing With Sin in the Church
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.
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.”
