Two tribes, Gad and Reuben, with half the tribe of Manasseh, had received their inheritance before crossing the Jordan. The wide upland plains and rich forests of Gilead and Bashan had attractions that could not be found in Canaan itself. The two and a half tribes, desiring to settle here, had pledged to supply their quota of armed men to go with their brethren across the Jordan and share their battles until they also would enter upon their inheritance. When the ten tribes entered Canaan, forty thousand of “the men of Reuben, the men of Gad, and half the tribe of Manasseh ... prepared for war crossed over before the Lord for battle, to the plains of Jericho.” (Joshua 4:12, 13). For years they fought bravely by the side of their brethren. As they had united with them in the battles, they also shared the spoils. They returned “with much riches ..., with very much livestock, with silver, with gold, with bronze, with iron, and with very much clothing”—all of which they were to share with those who had remained with the families and flocks. BOE 258.6
With a burdened heart Joshua watched them leave, knowing how strong the temptations would be in their isolated and wandering life to fall into the customs of the heathen tribes that lived on their borders. BOE 259.1
While Joshua and other leaders were still troubled with anxious worries, strange news reached them. Beside the Jordan, the two and a half tribes had erected a great altar similar to the altar of burnt offering at Shiloh. On pain of death, the law of God prohibited the establishment of any other worship than the one at the sanctuary—because it would lead the people away from the true faith. BOE 259.2
It was decided to send a delegation to get an explanation of their conduct from the two and a half tribes. Ten princes were chosen, one from each tribe. Their leader was Phinehas, who had distinguished himself by his zeal in the situation at Peor. BOE 259.3
Taking it for granted that their brethren were guilty, the ambassadors met them with sharp words. They told them to remember how judgments had come on Israel for joining themselves to Baal Peor. Phinehas told the Gadites and Reubenites that if they were unwilling to live in that land without an altar for sacrifice, they would be welcome to share in the possessions and privileges of the tribes on the other side. BOE 259.4
In reply, those accused explained that their altar was not intended for sacrifice, but simply as a witness that, although separated by the river, they were of the same faith as their relatives in Canaan. They had feared that in future years their children might be excluded as having no part in Israel. This altar, patterned after the altar of the Lord at Shiloh, would be a witness that its builders were also worshipers of the living God. BOE 259.5
The ambassadors accepted this explanation with great joy, and the people united in rejoicing and praise to God. BOE 259.6
The tribes of Gad and Reuben now placed an inscription on their altar pointing out the purpose for which it was erected. They said, “It is a witness between us that the Lord is God.” In this way they tried to prevent future misunderstanding and remove a possible cause of temptation. BOE 259.7
