Numbers 2:32-34

New Century Version

³² These are the Israelites who were counted by families. The total number of Israelites in the camps, counted by divisions, is 603,550. ³³ Moses obeyed the Lord and did not count the Levites among the other people of Israel.

³⁴ So the Israelites obeyed everything the Lord commanded Moses. They camped under their flags and marched out by families and family groups.
