And when they came unto 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 built there an altar by Jordan, a great altar to see to. (22:10)

And the children of Reuben and the children of Gad called the altar [Ed]: for it [shall be] a witness between us that the Lord [is] God. (22:34)
