Numbers 32
1 The tribes of Reuben and Gad owned huge herds of animals. They walked through the land of Jazer and Gilead and saw something amazing, this was the best land for their animals!
6 Moses fired back at Gad and Reuben, "Your brothers will march off to war while you sit here doing nothing?"
16 They stepped up close to Moses. "We will build stone walls here. Pens for our animals. Strong towns for our children."
