5 The Eternal One spoke to Moses.
Now that the arrangement of the camp, the ordering of the families, and the organization of their defenses is complete, God begins sanctifying the people. Because this camp is a holy place—a place where God has chosen to dwell among His people—purity is an obvious concern. But beyond the religious regulations, concern for cleanliness and rules for social interaction are essential because of the vast number of people traveling together. There are more than 600,000 males over the society’s average age of 20 years, and logically these men make up one-quarter of society. The laws given to the people are not simply religious instruction, but are necessary for the good morale and accompanying social concerns of such a large population, concerns such as transmission of diseases, mistreatment of individuals, and suppression of crime.
Eternal One: 2-3 Tell the Israelites to send outside of the camp anyone, male or female, who is ritually unclean and could spread it to others, namely those with skin lesions, and discharges, or who have touched a dead person. They need to stay outside of the camp in order not to ritually contaminate My dwelling place among them.
