What does Joshua 22:7 mean?

Now Yahweh your God has given rest to your brothers, as he spoke to them. Therefore now return and go to your tents, to the land of your possession, which Moses the servant of Yahweh gave you beyond the Jordan.

Only take diligent heed to do the commandment and the law which Moses the servant of Yahweh commanded you, to love Yahweh your God, to walk in all his ways, to keep his commandments, to hold fast to him, and to serve him with all your heart and with all your soul.”

So Joshua blessed them, and sent them away; and they went to their tents.

and spoke to them, saying, “Return with much wealth to your tents, with very much livestock, with silver, with gold, with brass, with iron, and with very much clothing. Divide the plunder of your enemies with your brothers.”

The children of Reuben and the children of Gad and the half-tribe of Manasseh returned, and departed from the children of Israel out of Shiloh, which is in the land of Canaan, to go to the land of Gilead, to the land of their possession, which they owned, according to the commandment of Yahweh by Moses.

When they came to the region about the Jordan, that is in the land of Canaan, the children of Reuben and the children of Gad and the half-tribe of Manasseh built there an altar by the Jordan, a great altar to look at.
