Hobab the Midianite, the father-in-law of Moses, was there. And Moses said to him, “We're leaving for the place the LORD has promised us. He has said that all will go well for us. So come along, and we will make sure that all goes well for you.”
Israel did everything the LORD had told Moses. They arranged their camp according to clans and families, with each tribe under its own banner. And that was the order by which they marched into battle.
