Matthew 18
15 Ref `And if thy brother may sin against thee, go and show him his fault between thee and him alone, if he may hear thee, thou didst gain thy brother;
16 Ref and if he may not hear, take with thee yet one or two, that by the mouth of two witnesses or three every word may stand.
17 Ref `And if he may not hear them, say `it' to the assembly, and if also the assembly he may not hear, let him be to thee as the heathen man and the tax-gatherer.
