Numbers 32:1-4

Now the children of Reuben and the children of Gad had a great number of cattle: and when they saw that the land of Jazer and the land of Gilead was a good place for cattle; The children of Gad and the children of Reuben came and said to Moses and to Eleazar the priest and to the chiefs of the meeting, Ataroth, and Dibon, and Jazer, and Nimrah, and Heshbon, and Elealeh, and Sebam, and Nebo, and Beon, The land which the Lord gave into the hands of the children of Israel, is a land for cattle, and your servants have cattle.
