² So the sons of Gad and of Reuben came and spoke to Moses, to Eleazar the priest, and to the leaders of the congregation, saying, ³ “[The country around] Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo, and Beon, ⁴ the land which the Lord conquered before the congregation of Israel, is a land [suitable] for livestock, and your servants have [very large herds of] livestock.”
