MAT 18:16

16 If that person will not listen to you [nor feel sorry that he has sinned against you], go get one or two other people [who will listen to what you both have to say]. Have them go with you so that [what is written] {[Moses wrote]} [in the Scriptures might happen:] ‘[When one person accuses another in some matter], it should be confirmed by [at least] two or three people {[at least] two or three people should confirm it} [before that person can be declared] guilty {[before they declare that person guilty]}.’
