Matthew 18:15-18 New American Standard Bible (NASB)
Discipline and Prayer
15 “If your brother sins[a], go and [b]show him his fault [c]in private; if he listens to you, you have won your brother. 16 But if he does not listen to you, take one or two more with you, so that by the mouth of two or three witnesses every [d]fact may be confirmed. 17 If 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 [e]a Gentile and [f]a tax collector. 18 Truly I say to you, whatever you [g]bind on earth [h]shall have been bound in heaven; and whatever you [i]loose on earth [j]shall have been loosed in heaven.
Matthew 18:15-18 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.
