The census totals given for each tribe in Bamidbar, over six hundred thousand fighting men once added together, imply a total Israelite population, including women, children and Levites, well into the millions, a figure many historians and demographers regard as difficult to reconcile with a group described as living off wilderness resources for forty years. Proposals to resolve the difficulty vary: some scholars argue the Hebrew word elef, ordinarily translated thousand, could in some early military contexts denote a smaller unit such as a clan or a squad rather than a literal thousand, which would sharply reduce the implied population, while others treat the numbers as a later, stylised literary figure rather than a historical headcount, and still other historians and most traditional commentators accept the numbers as intended literally. No single reading commands full agreement among specialists.
Source critics attribute the census material, with its careful tribal lists and precise figures, to the Priestly source, consistent with its highly organised, administrative style found throughout the opening chapters of Numbers.
Historians studying population figures elsewhere in the ancient Near East note that other surviving administrative and royal records from the period also used round, formulaic numbers for population and army size rather than figures resulting from an exhaustive count, a broader pattern some scholars cite in support of reading Bamidbar's tribal totals as a stylised literary convention of the era rather than as a precise field census, though this remains one proposal among several rather than a settled conclusion.
