Joshua 22:28-34 NASB

28 Therefore we said, 'It shall also come about if they say this to us or to our generations in time to come, then we shall say, "See the copy of the altar of the Lord which our fathers made, not for burnt offering or for sacrifice; rather it is a witness between us and you."'

29 Far be it from us that we should rebel against the Lord and turn away from following the Lord this day, by building an altar for burnt offering, for grain offering or for sacrifice, besides the altar of the Lord our God which is before His tabernacle."

30 So when Phinehas the priest and the leaders of the congregation, even the heads of the families of Israel who were with him, heard the words which the sons of Reuben and the sons of Gad and the sons of Manasseh spoke, it pleased them.

31 And Phinehas the son of Eleazar the priest said to the sons of Reuben and to the sons of Gad and to the sons of Manasseh, "Today we know that the Lord is in our midst, because you have not committed this unfaithful act against the Lord; now you have delivered the sons of Israel from the hand of the Lord."

32 Then Phinehas the son of Eleazar the priest and the leaders returned from the sons of Reuben and from the sons of Gad, from the land of Gilead to the land of Canaan, to the sons of Israel, and brought back word to them.

33 The word pleased the sons of Israel, and the sons of Israel blessed God; and they did not speak of going up against them in war to destroy the land in which the sons of Reuben and the sons of Gad were living.

34 The sons of Reuben and the sons of Gad called the altar Witness; "For," they said, "it is a witness between us that the Lord is God."
