Numbers 32:23-27

“But if you don’t do these things, you will be sinning against the LORD; know for sure that you will be punished for your sin. Build cities for your children and pens for your animals, but then you must do what you promised.” The Gadites and Reubenites said to Moses, “We are your servants, and we will do what you, our master, command. Our children, wives, and all our cattle will stay in the cities of Gilead, but we, your servants, will prepare for battle. We will go over and fight for the LORD, as you, our master, have said.”
