Moses assigned land to the tribe of Reuben ¹  by its clans.

The border of the tribe of Reuben was the Jordan. The land allotted to the tribe of Reuben by its clans included these cities and their towns. ¹ 

Merari’s descendants by their clans were allotted twelve cities from the tribes of Reuben, Gad, and Zebulun.

¹  from the tribe of Reuben: Bezer, Jahaz,

The Reubenites, Gadites, and the half-tribe of Manasseh crossed over armed for battle ahead of the Israelites, just as Moses had instructed them.

went up to Beth Hoglah, crossed north of Beth Arabah, and went up to the Stone of Bohan son of Reuben.

It went northward, extending to En Shemesh and Geliloth opposite the Pass ¹  of Adummim, and descended to the Stone of Bohan son of Reuben.

They went to the land of Gilead to the Reubenites, Gadites, and the half-tribe of Manasseh, and said to them:

The Reubenites, Gadites, and the half-tribe of Manasseh answered the leaders ¹  of the Israelite clans:

The Reubenites and Gadites named the altar, “Surely it is a Reminder to us ¹  that the Lord is God.”

But the Levites will not have an allotted portion among you, for their inheritance is to serve the Lord. ¹  Gad, Reuben, and the half-tribe of Manasseh have already received their allotted land ²  east of the Jordan which Moses the Lord’s servant assigned them.”

Beyond the Jordan east of Jericho ¹  they selected ²  Bezer in the desert on the plain belonging to the tribe of Reuben, Ramoth in Gilead belonging to the tribe of Gad, and Golan in Bashan belonging to the tribe of Manasseh.

The Reubenites, Gadites, and half-tribe of Manasseh came to Geliloth near the Jordan in the land of Canaan and built there, near the Jordan, an impressive altar. ¹ 

The Israelites received this report: ¹  “Look, the Reubenites, Gadites, and half-tribe of Manasseh have built an altar at the entrance to ²  the land of Canaan, at Geliloth near the Jordan on the Israelite side.”

The Israelites sent Phinehas, son of Eleazar, the priest, to the land of Gilead to the Reubenites, Gadites, and the half-tribe of Manasseh.

The Lord made the Jordan a boundary between us and you Reubenites and Gadites. You have no right to worship the Lord.’ ¹  In this way your descendants might cause our descendants to stop obeying ²  the Lord.

When Phinehas the priest and the community leaders and clan leaders who accompanied him heard the defense of the Reubenites, Gadites, and the Manassehites, ¹  they were satisfied. ² 

Phinehas, son of Eleazar, the priest, and the leaders left the Reubenites and Gadites in the land of Gilead and reported back to the Israelites in the land of Canaan. ¹ 

The Israelites were satisfied with their report and gave thanks to God. ¹  They said nothing more about launching an attack to destroy the land in which the Reubenites and Gadites lived. ² 

So the Reubenites, Gadites, and half-tribe of Manasseh left the Israelites in Shiloh in the land of Canaan and headed home to their own land in Gilead, ¹  which they acquired by the Lord’s command through Moses.
