Numbers 32:1-5

Now the sons of Reuben and the sons of Gad had a very large number of livestock. So when they saw the land of Jazer and the land of Gilead, that it was indeed a place suitable for livestock,

the sons of Gad and the sons of Reuben came and spoke to Moses, Eleazar the priest, and to the leaders of the congregation, saying,

“Ataroth, Dibon, Jazer, Nimrah, Heshbon, Elealeh, Sebam, Nebo, and Beon,

the land which the Lord conquered 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 as our property; do not take us across the Jordan.”
