Numbers 2:32-34

Contemporary English Version

³² So all the Israelites in the camp were counted according to their ancestral families. The troops were arranged by divisions and totaled 603,550. ³³ The only Israelites not included were the Levites, just as the Lord had commanded Moses.

³⁴ 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.
