Numbers 32:1-5

Now the people of Reuben and the people of Gad had a very great number of livestock. And they saw the land of Jazer and the land of Gilead, and behold, the place was a place for livestock. So the people of Gad and the people of Reuben came and said to Moses and to Eleazar the priest and to the chiefs of the congregation, “Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo, and Beon, the land that the LORD struck down before the congregation of Israel, is a land for livestock, and your servants have livestock.” And they said, “If we have found favor in your sight, let this land be given to your servants for a possession. Do not take us across the Jordan.”
