Numbers 2:32-34

New International Version - UK

³² These are the Israelites, counted according to their families. All the men in the camps, by their divisions, number 603,550. ³³ The Levites, however, were not counted along with the other Israelites, as the Lord commanded Moses.

³⁴ So the Israelites did everything the Lord commanded Moses; that is the way they camped under their standards, and that is the way they set out, each of them with their clan and family.
