He said that about the people you live in on a day to day basis. His vision was that the roman government would be abolished and the Jews would be able to live in peace and prosperity in small village communities without the need of any intervening court or government, and that small issues analogous to "a slap on the cheek" could be forgiven. But if someone continues to do you wrong, then that person wouldn't be forgiven.
"“If another member of the church sins against you, go and point out the fault when the two of you are alone. If the member listens to you, you have regained that one. But if you are not listened to, take one or two others along with you, so that every word may be confirmed by the evidence of two or three witnesses. If the member refuses to listen to them, tell it to the church; and if the offender refuses to listen even to the church, let such a one be to you as a Gentile and a tax collector. " Matt. 18:15-17
