Judges 20:12

¹⁴then you shall inquire, investigate, and ask diligently. Behold, if it is true, and the thing certain, that such abomination was done among you,

¹³The children of Israel sent to the children of Reuben, and to the children of Gad, and to the half-tribe of Manasseh, into the land of Gilead, Phinehas the son of Eleazar the priest. ¹⁴With him were ten princes, one prince of a fathers’ house for each of the tribes of Israel; and they were each head of their fathers’ houses among the thousands of Israel. ¹⁵They came to the children of Reuben, and to the children of Gad, and to the half-tribe of Manasseh, to the land of Gilead, and they spoke with them, saying, ¹⁶“The whole congregation of the LORD says, ‘What trespass is this that you have committed against the God of Israel, to turn away today from following the LORD, in that you have built yourselves an altar, to rebel today against the LORD?

¹⁸If it is possible, as much as it is up to you, be at peace with all men.

¹⁵“If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother. ¹⁶But if he doesn’t listen, take one or two more with you, that at the mouth of two or three witnesses every word may be established.¹⁷If he refuses to listen to them, tell it to the assembly. If he refuses to hear the assembly also, let him be to you as a Gentile or a tax collector. ¹⁸Most certainly I tell you, whatever things you bind on earth will have been bound in heaven, and whatever things you release on earth will have been released in heaven.

¹⁰When you draw near to a city to fight against it, then proclaim peace to it.
