To reassure the people concerning the divine bestowal of priesthood, Moses collects the staffs from the leaders of each tribe. He labels each staff with the name of its respective bearer, including Aaron's sacred staff, and arranges them in the temple. The subsequent legislation emphasizes that the priesthood is a sacred gift from God rather than a mere human appointment. To illustrate this, Moses presents the staffs on the altar, ensuring that the staff which is differentiated by a miraculous sign serves as a testimony to divine ordination.
