the children: This verse should probably be rendered, "And when they came to the borders of Jordan, that are in the land of Canaan, the children of Reuben, and the children of Gad, and the half tribe of Manasseh, Then built an altar by (or beyond, al) Jordan, a great altar to the view." It would appear, that when they came to the river, they formed the purpose of building the altar; and when they crossed it they put that purpose into execution. It is evident that they did not build it west of the Jordan, for that was not in their territories, and the next verse expressly says that it was built over against the land of Canaan.
