Joshua 22:29-34

Far be it from us to rebel against the LORD or turn away from him by building our own altar for burnt offerings, grain offerings, or sacrifices. Only the altar of the LORD our God that stands in front of the Tabernacle may be used for that purpose.” When Phinehas the priest and the leaders of the community—the heads of the clans of Israel—heard this from the tribes of Reuben, Gad, and the half-tribe of Manasseh, they were satisfied. Phinehas son of Eleazar, the priest, replied to them, “Today we know the LORD is among us because you have not committed this treachery against the LORD as we thought. Instead, you have rescued Israel from being destroyed by the hand of the LORD.” Then Phinehas son of Eleazar, the priest, and the other leaders left the tribes of Reuben and Gad in Gilead and returned to the land of Canaan to tell the Israelites what had happened. And all the Israelites were satisfied and praised God and spoke no more of war against Reuben and Gad. The people of Reuben and Gad named the altar “Witness,” for they said, “It is a witness between us and them that the LORD is our God, too.”
