Numbers 32:3-7

“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.”

But Moses said to the sons of Gad and the sons of Reuben, “Should your brothers go to war while you remain here?

And why are you discouraging the sons of Israel from crossing over into the land which the Lord has given them?
