I gave the Reubenites and the Gadites the land that begins at Gilead and goes from the Arnon Ravine (the middle of the Arnon is the border) to the Jabbok River, which is the Ammonite border.
Israel killed the king and captured his land from the Arnon River to the Jabbok River. They took the land as far as the Ammonite border, which was strongly defended.
But you did not go near the land of the Ammonites, on the shores of the Jabbok River, or the towns in the mountains, as the Lord our God had commanded.
