Numbers 2:32-34

32These are those that were numbered of the children of Israel, according to their fathers' houses: all those that were numbered of the camps, according to their hosts, were six hundred and three thousand five hundred and fifty. 33But the Levites were not numbered among the children of Israel; as Jehovah had commanded Moses. 34And the children of Israel did according to all that Jehovah had commanded Moses: so they encamped according to their standards, and so they journeyed, every one according to their families, according to their fathers' houses.
