Bible: census of adult men during the Exodus, by tribe

According to the book of Numbers in the Old Testament of the Bible, one year after Moses led the Israelites from Egypt during the Exodus, the number of men aged 20 years or older and available to serve in the Israelites' army totalled at 603,550 men. This census was conducted by Moses and the leaders of the 12 Tribes of Israel, with the clan of Judah contributing the largest number of men. However, only 11 of the 12 Tribes were counted, as the men of the Levites were tasked with protecting the tabernacle, which was the central mneeting and worshipping tent of the Israelitres' nomadic society during the Exodus.
