When Someone Hurts You - ERV
15 “If your brother or sister in God’s family does something wrong, go and tell them what they did wrong. Do this when you are alone with them. If they listen to you, then you have helped them to be your brother or sister again.
16 But if they refuse to listen, go to them again and take one or two people with you. Then there will be two or three people who will be able to tell all that happened.b
17 If they refuse to listen to them, tell the church. And if they refuse to listen to the church, treat them as you would treat someone who does not know God or who is a tax collector.
18 “I can assure you that when you speak judgment here on earth, it will be God’s judgment. And when you promise forgiveness here on earth, it will be God’s forgiveness.c
19 To say it another way, if two of you on earth agree on anything you pray for, my Father in heaven will do what you ask.

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.
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.
