TRADITION VS SCHOLARSHIP
The answer
Exodus 12:37 counts 600,000 men on foot. The two-million figure is an extrapolation from that, assuming 'elef means a literal thousand and adding dependents. Sinai surveys have turned up little — though a mobile group leaves few durable traces in any case. The heavier problems are logistical: water, food, and what a population that size would mean for Canaan on arrival.
Why it’s interesting
The debate isn't only 'did it happen' but 'at what scale' — a distinction that changes what we'd even expect to find. The Hebrew 'elef can mean a clan or a military unit as well as a thousand, so the headcount may never have been a headcount.
Genuinely debated
You can know the Bible.
Not just the stories, but the history, authorship, and scholarship behind it.
